The next step for telegram is pretty obvious. Stop collecting information about your users if you don't want to be forced to hand it over when given a valid government warrant. Of course that means they actually have to roll out E2E encryption by default so they probably won't do that.
Governments will just force user tracking and collecting data, and if you won't comply, you'll go to jail. If you're a legal business, there's no way to avoid three letter agencies messing with you and your users.
