Telegram hasn’t been secure since basically day 1. IIRC it went something like
Security experts: Never roll your own cryptography.
Telegram: We rolled our own cryptography!
Security experts: Don’t. And it’s broken.
Telegram: uhhhh… We fixed it.
Security experts: It still looks really bad. Stop it.
Telegram: says nothing
Corrupt politicians can simply ignore the law. If they didn’t ignore it, they wouldn’t be very corrupt.
