You are missing the point though. If I as a random person create a client with E2EE then if it is a good client otherwise or E2EE by default doesn't matter in the question "Are they doing a good job at cryptography". It would be like saying "That expensive and very beautiful plate sucks because the cake you put on-top of it is disgusting". Irrelevant to the discussion at hand.
>surely you can stop defending a random company, and take a rational stance and condemn Telegram for not deploying ubiquitous E2EE
Yes I can and I do by comparing Telegram to likewise badly made clients (like iMessage) but this is still beside the point that you seem to avoid: If they made a piece of software and have no professional knowledge of the area it was made for (cryptography/E2EE) then they are extremely good at what they are doing no matter if you like the default settings or not.
I don't use Telegram but this comment thread is nothing but a tirade against something because it is Russian. If you wanted to discuss the actual work then there's no reason at all to mention Russia. You criticize them and say a CS major can pull it off too and then try to argue their home country and default options are a proof of how vulnerable their software is. It is not proof. Code quality, default settings and where you live is not the same thing. Your comment is reading as "TL;DR Made in Russia, hence bad".
