I think the idea that the PDS servers "should" be neutral is unrealistic. If community servers are acting as de-facto infrastructure and you suppose that they "should" do something, well then, there's always an implicit enforcement mechanism standing behind the word "should". If you still need to invoke a centralized authority to make the players in a supposedly decentralized system work together, well, back to square one then. I will admit I myself have fallen into this kind of wishful "should" thinking before. And I think the reason why it's so easy to fall into is because the early internet had a lot of self-selected people that naturally aligned idea on certain values like curiosity, not assuming things about people, etc. But it's a different game now. I do think nostr is closer to a workable solution than bluesky, because nostr is fundamentally oriented toward redundancy/exit, not consistency/consensus. Notice that biological systems mirror this architecture.
