Can someone explain Why would Jack Dorsey support both Nostr and Bluesky, and have 1 billion USD (or, well, were 1 billion USD) in Twitter, why is this person competing with himself three ways?
My guess as to his motivation: he feels guilty about the fact he helped turn Twitter into a huge greedy company instead of an open world-changing protocol like HTTP or SMTP.
The problem is that he's fragmenting his efforts, it's like his effort capacity is 3 ants, and instead of telling all ants to pull the leaf in one direction, he tells each ant to pull in a different direction, so the leaf never moves.
Social networks are ALL about network effects. Split them up and they melt into obscurity. Combine them, they become untouchable.
