As the AI boom is minting billionaires by the day and the first trillionaires are now coming into view, one thing is becoming clearer and clearer: The battle between democracy and oligarchy will be the defining battle of the 21st century.

Good news from the US today. AICOA, a bill that cracks down on anticompetitive practices from Big Tech was re-introduced in the Senate with bipartisan support. My quote in the Senate press release explains why @ProtonPrivacy is supporting this legislation: judiciary.senate.gov/press/r…

Terrible, and also misleading because the "Common Sense Reforms" actually expanded the scope of surveillance without meaningful safeguards. Here's what actually happened during the "reforms" in the last reauthorization: brennancenter.org/our-work/a…

The problem for #bitcoin isn't that the debasement trade is wrong, it's just no longer the best asset class. Gold (the original) now has higher speculative returns with better downside protection. Recovery will be tough until this dynamic changes.

Proton’s contribution of humanitarian aid isn’t expressing a political opinion, it’s expressing our humanity. Politics has nothing to do with it.

To help alleviate the humanitarian disaster in Gaza, Proton has donated $100,000 to the Palestinian Red Crescent Society and other aid organizations working on the ground.

So Signal, which much of Europe also relies upon, apparently runs on AWS, which is not great from a tech sovereignty standpoint. An European alternative not run on Big Tech cloud will be necessary to safeguard strategic autonomy.

Now Firefox users can choose whether they want Google or Perplexity to collect their data.
Perplexity is now an in-built default search option for all Firefox users. We look forward to working closely with Mozilla on a lot more things in the near future.

e-ID passed in Switzerland by around 20'000 votes. Had we emailed our users in Switzerland, NO could have won, but we didn't want to interfere with the democratic process. However, state-owned companies interfered by funding the YES campaign. Calls for a new vote are justifiable.

Opposition to #ChatControl within Denmark is growing. Fast. If you are a Danish citizen, please sign this official petition: borgerforslag.dk/se-og-stoet… At 50 000 signatures, it is automatically submitted to the parliament and undergoes the standard legislative process.

Nvidia invests 100B in OpenAI, so OpenAI can buy more Nvidia GPUs (while increasing its own valuation), which in turn increases Nvidia's stock price, and the cycle repeats. For whose who haven't seen this movie before, this is late stage bubble economics. cnbc.com/2025/09/22/nvidia-o…

Even though Denmark (which holds the rotating EU council presidency) did not receive sufficient support for chat control today, they are trying to proceed anyways. Surprisingly, Sweden now supports breaking encryption, and this is the end of Sweden's reputation for privacy.

The EU’s Chat Control proposal has been stopped, for now, thanks to opposition from Germany and Luxembourg. But the fight isn’t over. We’ve been opposing this dangerous attempt to weaken encryption since 2022, and the EU will likely try again.

Important win. A court rejected Google’s effort to overturn a unanimous jury verdict finding that Google illegally monopolized key markets. The court also noted that digital monopolies can enjoy the fruits of their illegal conduct even after it stops. This means that a remedy may need to go beyond just stopping the illegal behavior so that the market can truly be opened up to competition.
