Nostr is the only one starting as an open protocol (that I know of).

Bluesky seems very closed, and even their proposed federation model is far from open. This is still governance, dressed up differently.

These villages you speak of can (and I would argue eventually will) all happen here, with different flavors, settings, filters, whatever… an open protocol lets this happen organically. Closed protocols by definition have an upper limit on growth. Sure they could somehow be part of this movement at the outset, but they’ll die out to an open protocol like Nostr eventually once it takes off
