Even on public instances, I don’t understand why people think defederating hurts the fediverse. Just join a different instance, how hard can it be?

I’m on 3 different instances right now

Do we have a way to combine feeds yet? I don’t know of one. So it’s kinda annoying to jump from account to account to make sure your seeing everything.

Sure, but keep in mind the comparison to any non-federated site has to be that you had no other instances to jump to in the first place.
