Maybe I'm wrong, but last time I checked, Telegram is not entirely "open source". The core part of the service is secret. Which kind of voids the whole 'open source' argument and actually makes this whole project doubly sneaky.. Also, open source does not automatically imply high quality or immunity from criticism. In this particular case, when people can be arrested or even executed for what they say (in some countries), this kind of code can be plain dangerous. Even if their intentions are absolutely pristine and they really want to do good in the world (which I hope they are) - a bit more diligence about the quality of the stuff you're sharing never hurts.
