Telegram continues trying to repair its reputation.

Does anybody really use Telegram for "privacy"? People can't seriously believe that thing is secure. Their FAQ indirectly states that group chats aren't encrypted and explicitly states that "secret chats" are.

We support two layers of secure encryption. Server-client encryption is used in Cloud Chats (private and group chats), Secret Chats use an additional layer of client-client encryption. All data, regardless of type, is encrypted in the same way — be it text, media or files.

I have never recommended Telegram to anybody. It's just like another facebook, AOL, ICQ, or whatever messenger. I actually don't personally know a single telegram user who uses secret chats. They are quite useless. They don't sync across devices.

Oh believe me, group chats are encrypted. Problem is, most of them are public, so that's only to protect them from being exposed to dump/search server side. And yeah, their encryption is not e2e. That's encryption nonetheless.

Are you talking about encryption at rest? Regardless, encryption by the server is worthless. It's exactly why admins can delete content in chat rooms.

Edit: that was over the top. My bad. It's not worthless. It's just doesn't really enhance privacy like E2E and I find it disingenuous to say "my chat app is encrypted" when you mean server encryption not E2E.

You're still missing the fact that public chats can't be adequately protected.

FWIW when they said that the "e2e" boom has yet to happen.

Depends what you mean by "adequately" 🤔 With perfect forward secrecy (which matrix and signal have), seeing past messages isn't possible. Seizing the servers is also not very useful unless people are connecting directly to the server. Anonymous public chats running on overlay networks like I2P and TOR might not even need encryption (although I wouldn't trust a server that didn't).

Where something publicly exists anyone can set up a local archive to capture anything, regardless of what's available at the moment of joining the chat. Also telegram has such a setting too. It's useless when someone really wants to get you. They won't need an access to telegram servers to get you.
