Earlier quoted context omitted.
Isn't the big sacrifice with Telegram security? I get that people like its UX, but if you're sacrificing security for UX then basically anything becomes fine?
For most people the said security is not a big issue. Esp. in countries where police can come for you and make you talk by any means. E2EE won't help you if they want you.
The police can only make you talk if they know who to make talk in the first place.
Reading your messages tells them who to interrogate, where to find them, who else is involved, etc.
Encryption is important especially in such countries.
