This all implies Bluesky can be considered a massive tech corp (which it honestly isn't even with investors, definitely not compared to Meta, or even Mozilla at this point), and can even be monetised.
In the event that they do attempt that, users can move to a different PDS and not lose any of their data - that's how AT was built. While on AP, it's dependent on if the software powering the account supports migration, and even then I've not seen an implementation that carries over all of the user's data (Mastodon only does followers/following, Lemmy has no migration whatsoever). That's not to say it's impossible, but I've not seen it happen.
Bluesky's development has been pretty democratic, moreso than Mastodon where one guy basically leads the entire trajectory of the fediverse (at least from a mainstream perspective) from what I heard.
As for Jack, hasn't been on Bluesky for a while now - he prefers Nostr. Even though he's on the board, he's not attended any meetings nor has he dictated how the platform should go. He just threw money at it and ran after the community didn't take him seriously.
