There's so much FUD here about how this must mean Telegram is now insecure, backdoored etc. I sure hope those voicing these opinions actually have used Telegram and understands how it works:
- Telegram does log chats server-side if you want them to (to be able to see your chat history across devices). You don't have to. Telegram supports end-to-end encryption ("secret chats") with no logging -- as far as I know there is no proof that these chats are untrustworthy.
- Telegram groups have never been sacred and they are deleted if they spread illegal information. This is not the same thing as leaking someone's personal chat history, which to my knowledge has still never been done.
I'd be glad to be proven wrong on any of these counts, I use both Telegram and Signal and trust the latter more for obvious reasons (it's completely open source) -- but the fact that Telegram is not perfect in every way does not make it insecure by default.
