Yes but Telegram continues to avoid fixing flaws that have been pointed out by cryptographers.

It's one thing to get some security wrong because its "hard." It's another to not fix those problems when people explain how and why you did something wrong.

RSA encryption is theoretically breakable by quantum computers, but people still use it and gonna be using it until someone break it.
