Bluesky's marketing department was Elon Musk. But your observations about nostr are true. At the same time, I'm not that worried about it, so long as 1. the best tech wins and 2. I can build a sustainable business on the protocol while staying decentralized. On the other other hand I recognize that "build it and they will come" is delusional. It all just depends on what the goals for the protocol are, and those vary widely.
