I think it's the "basically" part in basically right back where we started that makes the difference. Even if 100% of Fediverse users were on a single instance, once that instance starts pulling Musk moves, the users can move somewhere else.
Only if that instance defederates from everyone else do we get the Twitter situation again. Or, since that's actually what happened, Truth Social, which I think is just a slightly modified Mastodon instance with federation disabled/deactivated.

But this doesn’t happen. Mastodon.social is far from 90%, and the former CEO made the choice of letting control go to an entity that is no-profit, I think it’s the right choice.
