I don’t think there needs to be a war between protocols. Because this isn’t about profit or shareholders, making numbers go up is not really the important thing. What we are looking for is good methods to be social online. Experimentation with protocols has always been ok, as evidenced by the numerous RFCs.
I’ve looked at nostr and also the Bluesky architecture, and what I see there are different expressions of politics in code. They’re not my politics, but they’re somebody’s. In the nostr model there is no real incentive to run a relay, so that will become centralised, and the Bluesky architecture also looks designed to be centralised. Of course they will claim that it isn’t, because blockchains and such, but functionally there will be bottlenecks and a few wealthy people controlling those, as usual.
