I don't disagree, Nostr, APub and AT are all responses to the centralisation of social media in the 2010s and they all bill themselves as decentralised protocols, so should be discussed together. I'm just less trusting of Bluesky as they're VC backed and the general direction and vibe is very 'tech bro'. The lack of private blocks is endemic of that, private data being a thing that has to added and not considered important from day one. APub, on the other hand, has a very FOSS-esque culture, which is what I love about it and probably why it'll never go mainstream.
