Because I get asked a lot. Why we must fight Palantir, in brief. 1. Programmers working on the Internet have a moral responsibility to the entire world, not a single country. The Internet has been designed since its inception as a universal system for the sharing of knowledge without censorship. The Internet is not the property of any one government or nation. 2. The Internet enables mass surveillance at a scale unimaginable to the Gestapo and the Cheka. Far too many programmers have wasted their lives at building surveillance systems under the guise of Web advertising. Today, these web tracking systems are being used to monitor, control, and even kill humans by companies like Palantir that seek to combine state violence with corporate efficiency, and thus create a new form of technofascism. 3. Surveillance justified by external national security threats will be turned against citizens inside the nation-state. Mass surveillance was once the exclusive domain of the NSA, but today it has been privatized to corporations like Palantir that are unaccountable to any democratic process. What begins as fear of external foreign nation-states turns inwards to focus on immigrants, dissidents, and eventually to anyone that might challenge the status quo or try to exit an increasingly dysfunctional society. 4. Everyone is a target. The “enemy within” continually expands until it encompasses the entire population of a nation regardless of their status and beliefs, justifying evermore paranoid and totalizing surveillance. The line between policing and military operations blurs, with legal frameworks being replaced by technological violence operating with total impunity. 5. Surveillance can only be defeated by building software and hardware to defend ourselves. Meek calls for regulation or moralizing demands for human rights are useless in this era. Any rights must be enforced by the hard power of code. Code, not laws, can be used to uphold the right to privacy by making surveillance difficult, if not impossible, even by nation-state adversaries. 6. We are ruled by a senile gerontocracy. Unlike the generations that fought in the world wars, most of our current rulers are degenerate pedophiles who would sacrifice the well-being of the youth and the entire planet due to their infantile desire for wealth and power. Technology of surveillance and automated warfare reflects their increasingly desperate attempts to maintain archaic forms of domination. 7. The American Empire is unraveling. Once, the United States of America presided over a globe where it could enforce its rule via the status of the dollar as a global reserve currency and a network of equally global military bases, but new regional powers now directly challenge the United States as its empire dissolves in the face of internal economic stagnation, political corruption, and the inflation of the dollar. 8. In a real war, fantasies of total technological dominance always backfire. When a faceless drone kills a child’s father, that child will one day take revenge regardless of the cost, something forgotten by those raised in comfortable suburbs. Going beyond zero-sum games, one can only truly win a battle against a people by demonstrating your victory provides a better way of life, increased prosperity, and an inspiring philosophy. 9. Oddly enough, proponents of fully automated warfare support a universal draft. Deep-down, these keyboard warriors know that their technofascist fantasies are a paper tiger when up against determined opponents that engage in asymmetric warfare. They also know none of their children will fight in a war for their state but they would be happy to see other people’s children come home in body-bags. 10. The problem is not whether AI weapons will be built; we must hold responsible those who are building them. No matter which country is deploying automated killing machines, no one is absolved from the murder of civilians and the destruction of infrastructure due to the parlour-trick of shifting the blame to AI. 11. Atomic war is on the horizon. As various states descend into wars over increasingly scarce natural resources, the possibility of tactical nuclear strikes over Teheran, Kyiv, and other areas of conflict has returned to the historical stage. Increasingly geriatric and authoritarian rulers face less guardrails than before to deploying nuclear weapons, and may even be willing to sacrifice the survival of humanity to appease their own petty egos. 12. Our goal is a world of peace where every person can be empowered by the Internet. Modern war is the quintessential game of sending young people to the meat-grinder. Why die for the profit of corrupt rulers when one could build real wealth and power for yourself using the Internet? 13. We should fight for the world we want, and build the tools needed by future generations. Pacifism would be suicidal in this period of global turbulence and resource wars, but real hard power lies in technology: Programmers should be creating technologies to live a free life and prosper in a hostile society of surveillance and control, and decentralization is the only way these technologies will survive against the inevitable repression. 14. The State will not help us. The state is a dying pre-Internet institution that increasingly resembles nothing but a Ponzi scheme fueled by taxes and debt. None of the youth alive today will likely inherit any benefits, such as welfare and health care. 15. Centralized and opaque algorithms are a danger to free speech. Propaganda is the flip-side of surveillance, as continual propaganda prevents anyone from even thinking of challenging the system. Social media monopolies promote propaganda to create a generalized idiocy while silencing those that would dare to criticize the reigning order before they can organize against it. 16. Building new forms of social organization with each other is vital to survival. The traditional mediascape of politics and entertainment exists to distract us from building networked solidarity and distributed autonomous organizations across borders. The hierarchical state is as relevant to us as the medieval church and kings were to the formation of the joint-stock corporation and the labour union. 17. Digital identity is the next step in their system of control. Within the next few years, access to the Internet–including in Europe and the United States–will require biometric national identity cards, using the flimsy excuse of “protecting children.” The real goal is to gatekeep free access to subversive political content and halt cross-border communication in order to prevent new forms of self-organization and resistance from emerging. 18. Only when one can be anonymous is one truly free. The freedom to express oneself without censorship and surveillance is a vital precondition for both the autonomous use of reason and the democratic evolution of society. Technology must enable the freedom to selectively reveal ourselves to the world–so that we can become who we want to be–by preserving the right to privacy over the Internet, including not just individual privacy but the right to transact and form contracts privately. 19. America created the first global surveillance state, but it will not be the last. Too many have forgotten or perhaps taken for granted the revelations of Wikileaks and Snowden. States across the world from China to Russia are creating even more powerful global surveillance systems and propaganda machines. Leveraging private defense contracts in countries across the world, Palantir seeks to make itself the operating system of a cross-border global secret state while it pushes its own farcical version of ethno-nationalism. 20. Culture wars are a psyop. It is ironic that “Epstein class” virtue-signals about traditional morality and the superiority of forms of ethno-nationalism, while trying to return to the rule of hereditary elites, even in the United States. Rather than reverse the gains of the Enlightenment, we take the side of our ancestors who fought a centuries-long battle for individual liberty, scientific progress, decentralized markets, bottom-up democracy and the emancipation of humanity from feudal monarchs and their make-believe mythologies. 21. New forms of technology can reshape the world. Technology is not just a tool, but the world we live in and an extension of our cognitive capabilities. The co-operation of humans with the collective intelligence embedded in AI could accelerate human progress and overcome planetary crises such as climate change and atomic war that threatens the survival of our species. 22. Live free or die trying. We must bear eternal vigilance in the struggle against fascism, and the battlefield is technology. There is no middle ground: Technologists must choose whether to work for the enslavement of humanity or to create new spaces for freedom. These are my personal beliefs, not those of @nym. Yet as a philosopher that founded a tech startup, I have a responsibility to respond to this manifesto of Palantir and it's so-called "philosopher-CEO" Alex Karp.

7 DAYS TESTING @nym — WHAT ACTUALLY HAPPENS UNDER THE HOOD WHEN YOU HIT CONNECT? Most VPNs promise privacy. But there's a question we rarely ask: What happens to your data after it leaves your device? For years, my routine was pretty much the same as many Web3 users. Switching VPN regions to access AI tools like Claude, checking encrypted chats, and signing DeFi transactions. I assumed an encrypted VPN connection was enough. After spending time exploring @nym, I wanted to look beyond the usual "no-log" promises and understand what actually happens when you press Connect. I recorded a 30-second connection session. A few details caught my attention. 1. The problem with traditional VPN architecture A conventional VPN encrypts your connection and routes it through the provider's infrastructure. But encryption doesn't automatically mean anonymity. Your VPN provider may still observe your original IP address and connection metadata. Websites see the VPN's exit IP instead of yours, but the trust has largely shifted from your ISP to the VPN provider. That's an important distinction. Protecting data is not the same as hiding communication patterns. 2. What happens inside a NymVPN connection? Looking closely at my screen recording, three moments are worth examining: 00:11 — Zero-Knowledge Credentials The app displays "Downloading ZK-Nyms." Nym uses zero-knowledge credentials called zk-nyms to prove entitlement to network access without directly linking that access to the payment account. This is an important part of its privacy architecture, particularly for Mixnet access. 00:13 — Entry & Exit Separation Using the Auto connection preset, NymVPN selected: • Entry: Hong Kong — NYMers.com GW #4 • Exit: Cambodia — Oceanus Cambodia KH 1 This is where decentralized routing becomes interesting. The entry node can identify the incoming IP, but doesn't learn the final destination. The exit node can see where traffic is going, but doesn't know the user's original IP. Neither node alone has the complete picture. 00:25 — Community-Operated Infrastructure Opening the server selector reveals independent operators, including: • VinlexNodes | Nym Staking • NYMers.com GW #4 At the time of my recording, the mobile app displayed 642 servers across 70 countries. Instead of relying entirely on one company's centralized infrastructure, Nym distributes network operations across independent participants. 3. Two modes, two different privacy priorities This is probably the most interesting part of NymVPN. It doesn't force every user into the same connection model. ⚡ Fast Mode — 2-hop dVPN Uses decentralized AmneziaWG routing through entry and exit nodes. Designed for everyday browsing, streaming, AI workflows, and activities where connection speed matters. 👁️ Anonymous Mode — 5-hop Mixnet This takes a different approach. Traffic passes through: Entry Gateway → Mix Node 1 → Mix Node 2 → Mix Node 3 → Exit Gateway. The Mixnet combines multi-layer encryption, packet mixing, cover traffic, and timing delays to make traffic analysis significantly harder. The trade-off? Higher latency. But for private messaging, email, and sensitive crypto transactions, protecting metadata can matter more than minimizing response time. 4. Privacy needs more than another VPN subscription Nym's philosophy is built around a bigger idea: THE NEW INTERNET IS UNCENSORED. Privacy should not depend on blindly trusting a single company with your entire connection. What makes Nym interesting to me isn't simply that it changes your IP address. It's the attempt to rethink how online traffic is routed, how trust is distributed, and how metadata can be protected at the network level.

This is why you need @nym VPN even if the provider says no logs.
Seven VPNs. every one of them said “no logs.” july 2020: researchers found their shared database sitting open on the internet. no password. 1.2TB of data. over a billion log entries. inside: plaintext passwords, IP addresses, connection timestamps, websites visited, home addresses, emails, payment info. UFO VPN’s explanation: covid staff changes meant firewall bugs got missed. also, the logs were only for “performance monitoring” and were anonymized. the researchers checked the samples. they weren’t anonymous. the logs they swore didn’t exist were the ones that leaked.

This spring at the Salon des Batailles in the Hôtel de Crillon, Nicolas Lerner, head of French intelligence, asked me to ban conservative voices in Romania ahead of elections. I refused. We didn’t block protesters in Russia, Belarus, or Iran. We won’t start doing it in Europe.

Government surveillance used to be limited by both the amount of work it took to track the movements of a single person and protections of the 4th amendment. AI eliminates that first part, and the robust market for the digital breadcrumbs AI can use makes it trivial to sidestep the second. The warrant has been replaced by an invoice. open.substack.com/pub/protec…

I am having a perfectly peaceful and joyous Diwali here in India, and I am ashamed of the absolute racist idiocy in Seattle. I hope we can deport these “activists Jake and Thomas” to some sort of isolated island as they lack the common decency to be around other humans.
HAPPENING NOW: Absolutely chaotic scene as conservative activists Jake Lang and Thomas Allen storm a Diwali Hindu celebration at the Seattle Center Armory. They held signs that read, "Deport All Dot Heads" and "Stop Hindu Replacement of Christians." I just spoke to both men who say they are concerned about American culture being overrun by false idol worshippers and H1-B fraudsters. Lang and Allen say they will be targeting other locations in the city this weekend. They have yet to announce details of their plans due to possible retaliation by Antifa and other far-left activists. Stay tuned. @JakeLang|@Tommy4Trump420

Even a private transaction can reveal who sent it as access layer traffic can leak network metadata. Nym's SDK runs the mixnet in the browser with no install and no config, so wallets and dapps can tunnel their traffic through it and hide who's sending.
At DEVCON India @_wjth "The Nym Mixnet works today. With over 700 Independent node operators. " Wallets can intergrate the Nym Mixnet into their wallet giving users strong network security seamlessly via our SDK.

Given @gnosis_ just got hacked and leaked customer personal information (including customer wallet addresses!), how do they expect people to trust their upcoming @Gnosis_VPN? Unlike @nym VPN, @Gnosis_VPN appears to create wallet addresses that dox its users onchain too.

Hey @koeppelmann - GnosisVPN has literally 8 centralized permissioned exit nodes. Seems like the P2P element is still “in development” by @Gnosis_VPN after two years? Also, why run Wireguard inside a “default” one-hop mixnet? Doesn’t really make sense from a cryptographic security perspective. You want network tunnel to encrypt/authenticate between nodes then ship Sphinx packets inside tunnel.
GnosisVPN (p2p and thus harder to block) can’t come fast enough.

Two years later @Gnosis_VPN is running permissioned exit nodes ran by a centralized entity. Or you can try NymVPN from @nym that works in censored countries like Russia and China, and some nodes let you watch videos. And get a real mixnet for free at DevCon!
A problem we are focused on is this 👇 The north start for GnosisVPN is a VPN that does not look like a VPN to other participants.
