The purpose is like email, you can access multiple servers controlled by different groups from your own server controlled by people you’ve vetted.
But that’s just it - when these different groups betray us we are enabled by federation to move to a different server. In this case, the admins failed the vetting process.
If your email service started doing shit you didn’t like, such as forcing you to deal with spam email instead of blocking it, then you’d move to a different service.
But what if your email did shit like that every year? Or now you have to switch messaging with a group of friends and some don’t want to jump to a certain new app?
