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.

There has been multiple breaks, like the good old 2^64 bruteforce attack when they used too short session identifiers, malleability issues that could let the server/hackers change your messages, reordering attacks, etc.
What the issue with them storing the public key?
Aside from not storing anything you don’t absolutely need to store, there shouldn’t be an issue there.
