It’s really obvious this wasn’t a bug, but a backdoor. It proves that Telegram is an actively hostile adversary, the fact that their encryption scheme hasn’t been publicly broken since then doesn’t change that.

You might argue that their deliberate decision to not encrypt most chats is exactly that, more of a front door really.
Telegram is a bad actor.
Do you have any recent bugs? Or 'backdoors'? All their official apps are open source and reproducible. Must be easy to find bugs for security researchers. They even offer much larger bounties compared to other apps.
Anything? I want to believe people saying bad crypto, but it looks like there's no actual proof.
Here's something that says it is good, published more recently.
