Finally got rid of telegram, congratulations to me
It was a many months transition, and it's finally done
Fun thing, you can actually make a backup of all* your messages, groups, contacts, etc. So before leaving you can have all of your data in case you need that one contact or something
The final red flag was as that allegedly Russian authorities were messing with people's deleted messages. Not for the first time there are news that they could read, modify, delete, see location, and etc. Screw it, this is unsafe, I'm out.
Also, these days telegram is really at the state of a pile of garbage, bloated, buggy, and shady messenger.
Also Telegram's E2EE chats don't work on desktop apparently, and you are not able to see message contents in the notification (which is a plus or minus depending on you)
Asked a friend earlier today if we could use secret chat. He declined because he mostly chats on desktop, and apparently wants to see messages from notifications while driving.
Whatsapp is built on the Signal E2EE protocol, Telegram has a terrible homebrew encryption protocol with a ton of weirdness and it has had a long history of weaknesses which they lied aggressively about
