Jack Dorsey left Bluesky's board in May. I don't believe he has anything to do with the company anymore.

The CEO of Bluesky is Jay Graber. (Who despite the name is a Chinese woman.)

Jack got mad that people were making fun of him for being into crypto, left for another decentralized service Nostr, did too many psychedelics and fried his brain, then moved back to Twitter.

Jack invested to get BlueSky moving, and his company has been a major investor since the beginning. He also invested in Nostr. Only just this last week did his company divest from a lot of their social media stuff and invest in Crypto instead (given the company's basis in the US and recent politics that experts are predicting a decline in social media and huge increases in crypo ventures)
