The biggest surprise for me was the https://hexbear.net count, an instance I hardly interact with.

There's absolutely nothing wrong with a little centralization in your federation. It works well enough for email. The point is that you have the option, not that you have to use it.
You don't have to trade one extreme for the other. In fact, I think this is the perfect example of that. Lemmy.ml is the developers' instance, and by default would likely be the largest. Except... you know. Many, many people started there before going to other instances, especially the largest competitor.
The issue is that the kid that owns the ball sets the rules. LW could do something heinous, and the only choices would be to cope or lose half the Fediverse.
The thing is that the value is in the communities and not in the old content. So most likely the mods would just post we move to a new instance and a lot of users would follow. We just saw that on the German speakin lemmy instance feddit.de, which was abandoned and now most of the users and communities moved to feddit.org, which is already one of the larger ones.
What lemmy really needs is the ability to easily move accounts and communities. Mastodon has that for users already.
Mastodon still doesn't allow to move posts and comments
