If one were to have real proof, then would they not hold them out for a paying customer?

In light of that hypothetical but far-fetched pathway, there is probably no need for you to repent there.

I think we are talking past each other.

With WhatsApp the claim was that if someone snuck a backdoor into it there are enough people watching it to make sure that it would be found out soon.

My point is that even more people are sceptical to Telegram and even dislike it strongly so there should be even better chances of someone discovering if something was broken.

The colored highlighting of the code regions in Telegram executable by IDA-Pro has left me skeptical.

If you are still here, what do these regions and the fact that they are colored mean?

I'm honestly interested.

I only intend to defend Telegram against lies (most of the time the claim that "it is not encrypted"), not to cover up any actual problems so if you comment on it or write a post about it I will read it and probably will upvote it.
