Absolutely. I don't think it's really sunk in generally that the Fediverse is intended to operate fundamentally differently from a centralized system. An instance selectively (de)federating is how it's supposed to work.
If the platform running as intended kills it, then there are big problems. I don't think it will, but the user culture does have to change and incorporate knowledge of how the system works. We need to not have threads saying the Fediverse, a platform built on decentralization, needs to centralize as much as possible to survive.
Agreed!
People keep talking about the appeal of the megacommunities on Reddit, and I'm like... were they really that great? There was so much noise to sift through to get to anything real. Having decent discussions or building communities? Maybe if you're in a small niche subreddit, but otherwise no.
