Similar to bitcoin, nostr is an open book for all to see, which I am okay with. There are easy enough ways to do pseudonymity in these open systems if you need/want it, but as you point out the asymmetry of the three letter data hoard is a problem we can begin to address. If folks require absolute privacy, I am not sure nostr is the right protocol for them. I think we should at least have open datasets where it is possible. AI frameworks are open enough but the up-to-date data is not. The tech giants are really all data hoarders and they monetize those hoards selling to advertisers, ngos, governments, and private firms. Not really much access for plebs, which will reduce the impact of pleb-driven AI tech.
