Here’s what he said in a post on his telegram channel:
🤫 A story shared by Jack Dorsey, the founder of Twitter, uncovered that the current leaders of Signal, an allegedly “secure” messaging app, are activists used by the US state department for regime change abroad 🥷
🥸 The US government spent $3M to build Signal’s encryption, and today the exact same encryption is implemented in WhatsApp, Facebook Messenger, Google Messages and even Skype. It looks almost as if big tech in the US is not allowed to build its own encryption protocols that would be independent of government interference 🐕🦺
🕵️♂️ An alarming number of important people I’ve spoken to remarked that their “private” Signal messages had been exploited against them in US courts or media. But whenever somebody raises doubt about their encryption, Signal’s typical response is “we are open source so anyone can verify that everything is all right”. That, however, is a trick 🤡
🕵️♂️ Unlike Telegram, Signal doesn’t allow researchers to make sure that their GitHub code is the same code that is used in the Signal app run on users’ iPhones. Signal refused to add reproducible builds for iOS, closing a GitHub request from the community. And WhatsApp doesn’t even publish the code of its apps, so all their talk about “privacy” is an even more obvious circus trick 💤
🛡 Telegram is the only massively popular messaging service that allows everyone to make sure that all of its apps indeed use the same open source code that is published on Github. For the past ten years, Telegram Secret Chats have remained the only popular method of communication that is verifiably private 💪

There’s no reason for secret chsts to not be stored on the server and to not be synced to all your devices. We’ve had double ratchet for a while. Telegram rolling their own crypto is dumb for many reasons
Correct me if I’m wrong, but even with double ratchet, retrieving and decrypting the message history is tricky / impossible, no? Afaik signal does allow you to receive new messages on multiple “linked devices”, but a new linked device doesn’t have access to any messaging history.
That behavior would be a major improvement to telegram
From a privacy POV, sure, not trying to argue that. Just saying that Telegram does have a bunch of features like that that wouldn’t really work if all chats were always E2E encrypted, so there’s a reason that it’s opt-in. Whether it’s a good one or not is up to you to decide for yourself.
Though I definitely think that Telegram could do a much better job explaining the trade-off, especially in a world where many major messengers are always e2e encrypted, and people somewhat expect it to be the default.
