yes I know how tls works, thanks. my point is if they did care, they’d enable e2e by default. but they don’t, because they know that the average user will just not use it. They even don’t have a setting that says “I want all my chats to be encrypted”. you have to opt in, for each individual conversation. manually.
if you want a secure messaging app, use one that encrypts by default, so it’s impossible to mess it up. Telegram is not it.
