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.

Are there any programs that can do e2e in a group chat? My limited knowledge of e2e and encryption makes me think that'd be extremely difficult and even clunkier

Messages app by Apple. Not extremely difficult, but has its trade offs, and easier when all devices share a CA.
