I'm starting to think that this Telegram CEO crap is just some publicity stunt/psyop. As I have stated multiple times, both Telegram and ProtonMail are honeypots and are not to be trusted, both thriving on the fact that most people don't know how encryption (especially E2EE) truly works.
Anything that doesn't allow you to encrypt messages client side before sending to the server should not be trusted.
