I wouldn’t put Telegram at that level. I would put it in “The Brainwashed.” Its encryption is disabled by default. You need to manually enable it on each chat, and you can’t enable it on group chats. The app gives a false sense of privacy. Telegram flaunts its end-to-end encryption, but it never mentions that it is disabled by default, and it refuses to enable the default. The final result is that people are not using the feature.
A cryptographer and professor wrote a good piece about Telegram’s encryption, calling it “unusual” and the “non-standard authenticated encryption mode ever invented”: Is Telegram really an encrypted messaging app?
