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.

Assuming that data that can be leaked is being leaked is the only sensible thing to do if you care about privacy.

Aint this is the rule among cryptography types anyway?

Right, and it's strange to me that such a fundamental rule is being ignored when it comes to Signal. All of a sudden people start making all kinds of excuses as to why it's not a problem in this case.
