But all of that aside, Telegram has none of these things. Telegram is straight-up unencrypted with their default chats and group chats. Telegram is absolute dogshit.

So, that’s why they call PUBLIC chats in first place. In private chats all work exactly like in signal (DH end-to-end crypto with key verifying). But after 5 years some journalist finally read the documentation and newspapers was exploded. I known that from first day.

Telegram also honestly declares that there is no need to rely on anyone in matters of privacy. For example: We do not store customer IP, says signal developers. And how should I check it? Teleram just honestly says, “You have an mtproto proxy, build any kind of proxying chains and we won’t even theoretically know your address.” Feel the difference.

And I still don’t understand why MITM can’t just match two DH keys so that Alice and Bob’s signature checks match. But maybe I just don’t understand the cryptography chain well.

I don’t want tell that signal have bad crypto or telegram greates private messager. I say that all of that messengers have same security in private messages. Yes, signal support group private chats too, but that’s all. And if anyone can’t read docs, that not a telegram problem.
