Is Telegram really an encrypted messaging app? (blog.cryptographyengineering.com)

Blog post by crypto professor Matthew Green, discussing what Telegram does (I wasn't familiar with it) and criticizing its cryptography. He says Telegram by default is not end-to-end encrypted. It does have an end-to-end "secret chat" feature, but it's a nuisance to activate and only works for two-person chats (not groups) where both people are online when the chat starts.

It still isn't clear to me why Telegram's founder was arrested. Green expresses some concern over that but doesn't give any details that weren't in the headlines.

Element (really any Matrix client that supports e2ee) but rooms with hundreds I'd people and having encryption enabled is going to to have lots of messages with key exchange errors.
