"With Telegram it's possible to delete messages for everyone" If the phone is in airplane mode, or faraday bag it's not receiving any "delete message" commands. Also, with Telegram the case is, when the Belarusian, Russian, Chinese, Israeli, US... intelligence agency compromises the server, they can see every group message of every group, because by design Telegram's group chats never use E2EE. Every cryptographer agrees Telegram's encryption is shit. Let's start believing them.
