>Unless you have another interpretation of the Hanlon's Razor, it seems that he is saying this is a mistake and not a backdoor.

It just sounds like the author simply doesn't want to get sued, after all it's generally impossible to prove that a backdoor is actually a backdoor.

>people do dumb mistakes with self-rolled crypto all the time

I've seen a plenty of those, this one just happens to look rather different than the typical implementation mistakes you see. There's no possible reason for this code to exists except to allow Telegram to decrypt secret chats.

In the end, we've got nothing to gain and a plenty lose by giving Telegram the benefit of the doubt.

Well, sure. It's very possible indeed. I am still wondering why though -- Durov fled Russia, settled in UAE and then backdoored Telegram? Don't know. If a conspiracy becomes too complex then we all know what the other razor law says, right (Occam's)?
