So we remain vigilant & deeply grateful to our allies. For Signal, Chat Control is an existential threat. If we were *forced* to choose between building surveillance into our services or keeping our integrity, we would choose integrity & leave the market. We hope it never comes

The technical consensus is clear: you can't create a backdoor that only lets the "good guys" in. However they're dressed up, these proposals create cybersecurity loopholes that hackers and hostile nations are eagerly waiting to exploit. 6/

The reality is that scanning any content before it is encrypted negates the very purpose of encryption and is a dangerous backdoor. No amount of tinkering or word games can change that inescapable reality. 5/

We must be wary of "new" proposals that allow scanning of "known content" while claiming to protect privacy by proscribing "indiscriminate" surveillance. We must also look out for those that mandate only scanning for “hashed images or videos.” 4/

The war is not over, however. Now we move to the European Council, where the issue is unresolved. We expect closed-door negotiations to engage in rhetorical arbitrage--claiming to support privacy by using word games and bespoke definitions--while in practice undermining it.

Defending privacy isn't easy. Those in power always want more access +more info. It's especially hard when emotionally charged args are used to advance surveillance ❤️ to those doing the work!

We're so relieved to see Germany reaffirm its opposition to the dangerous Chat Control proposal--the one that would mandate mass scanning of communications. Germany's long been a solid champion of privacy, and the news that it was considering backing mass surveillance was

📣 Germany is close to reversing its principled opposition to mass surveillance & private message scanning, & backing the Chat Control bill. This could end private —& Signal—in the EU. Time is short and they're counting on obscurity: please let German politicians know how

EU #ChatControl threatens to implement automated scanning of all private online communications. We want a future without mass surveillance and with the right to our privacy! A backdoor for governments is a backdoor for everybody! We call on @bmjv_bund to hold the line!

We are alarmed by reports that Germany is on the verge of a catastrophic about-face, reversing its longstanding and principled opposition to the EU’s Chat Control proposal which, if passed, could spell the end of the right to privacy in Europe. https://t.co/015qmQnIS2

In 2023, Signal was the first mainstream messenger to enable post-quantum cryptography. We’re still ahead of the (elliptical) curve, implementing a new hybrid PQ ratchet ensuring Forward Secrecy & Post-Compromise Security even in a post-quantum world.

I think @mer__edith has made it clear that @signalapp would withdraw from EU countries if ChatControl proceeds. I suspect others would too rather than undermine their E2EE. I really hope the EU decide against this act of self-harm.

Of course it’s not that hard…if you define intelligence in the simplest least expansive most gameable terms. The issue becomes who gets to define intelligence & how. And once we open that box we’re back to grappling w the Mismeasure of Man, IQ testing’s sordid history, etc

On AI Agents... "...there is a powerful tension between privacy and security, on the one hand, and the vision of letting a complex system with broad access to your data do whatever it wants, on the other." - @mer__edith https://t.co/FYN8Cc7ane

Wow. I knew @mer__edith was amazing, but this is astonishing anyway. In a few minutes, she demystifies Silicon Valley’s VC culture & pierces the hype around GenAI. This is truly must-watch TV. 🔥🔥🔥🔥🔥/4
