Our statement on the UK government’s demand that all content on all devices sold or used in the country be scanned, on the presumption of nudity, using a dystopian combination of age verification and content scanning. This proposal will not safeguard children. It endangers us all.

This cannot be repeated enough.
Not just because it’s true, but because when people believe the lie that Telegram is private and secure, they can put themselves and the people they communicate with in danger.
Founder of @signalapp, @moxie Marlinspike on Telegram:
"Telegrams not a private messenger. There's nothing private about it. It's the opposite. It's a cloud messenger where every message you've ever sent or received is in plain text in a database that telegram the organization controls and has access to it"
"It's like 'Russian oligarch starts unencrypted version of WhatsApp', a pixel for pixel clone of WhatsApp. That should be kind of a difficult brand to operate. And somehow, they've done a really amazing job of convincing the whole world that this is an encrypted messaging app and that the founder is some kind of Russian dissident, even though he goes there once a month, the whole team lives there, and their families are there."
" What happened in France is they just chose not to respond to the subpoena. And so that's in violation of the law. And, he gets arrested in France, right? And everyone's like, oh, France, but I think the key point is they have the data, like they can respond to the subpoenas where as Signal, for instance, doesn't have access to the data and couldn't respond to that same request. To me it's very obvious that Russia would've had a much less polite version of that conversation with Pavel Durov and the telegram team before this moment. "

📣🚨 BAT SIGNAL: A law in France that would mandate a backdoor in end to end encrypted communications is set for a vote within the next day, after some start-stop skirmishes.
The French Narcotraffic law would require encrypted communications providers—like Signal—create a backdoor by giving the government the ability to add themselves to any group or chat they like. In the name of (checks notes) fighting drug trafficking.
While those hyping this bad law have rushed to assure French politicians that the proposal isn’t’ ‘breaking encryption’ their arguments are as tedious as they are stale as they are laughable. For those catching up, let’s review the basics: end to end encryption must only have two ‘ends’—sender and recipient(s). Otherwise, it is backdoored. Whatever method is devised to add a ‘third end’ —from a perverted PRNG in a cryptographic protocol, to vendor-provided government software grafted onto the side of secure communications that allow said government to add themselves to your chats—it rips a hole in the hull of private communications and is a backdoor.
Indeed, the ghost participant proposal was roundly rebuked (humiliated, even) when it was first proposed in 2019 in the UK. The technical community was united, and it was never implemented in law or otherwise.
We cannot accept any backdoor, however it’s dressed up. Communications don’t stay within jurisdictional boundaries. Which means a hole created in France becomes a vector for anyone wanting to undermine Signal’s robust privacy guarantees, anywhere. Instead of contending with unbreakable math, they only have to compromise a French government employee, or the vendor-provided software used to sideload government operatives into your private chats.
This is why, as always, Signal would exit the French market before it would comply with this law as written. At this moment especially, there is simply too much riding on Signal, on our being able to forge a future in which private communication persists, to allow such pernicious undermining.
We hope—WE HOPE—that this callow, dishonest attack will fail, and will be the last. We would love to get back to the work of maintaining and improving our core technologies, instead of fighting legislation which is distinguished in nothing as much as its refusal to listen to decades of expert consensus in its drive to imperil global cybersecurity and the human right of privacy.
