Re: recent #nostr drama, I've seen this same censorship debate played out, and end, over on #Hive (old Steemit) for years. There, clients (called front ends, main ones being PeakD, Ecency, hive.blog) censor out hate-posters and such. However, the posts are still there on the chain base layer and can be seen in any chain explorers. This would be like nostr notes on relays.
Bottom line, individual clients/ front ends can do whatever they want. Censor, filter, or show. If you don't like the censoring or showing, use another client or build your own. This is how decentralization works.
