On the fediverse we also see a lot of accusations of Bluesky being owned by Jack Dorsey, and this isn't true. My understanding is that Jay performed an impressive amount of negotiation to allow Bluesky to receive funding independently.
These days Jack Dorsey is instead focusing on Nostr, which I can only describe as "a sequel to Secure Scuttlebutt with extremely bad vibes where bitcoin people talk about bitcoin"
