One other critical bit of "censorship" and "oppression" that Nostr very much wants to route around is any restrictions on use of Lightning et. al. cryptocurrency payments directly in Nostr clients, without any intermediaries or custodians in the way. (This fear of "economic censorship" seems to be a common boogieman in cryptocurrency circles, from what I can tell. Certainly a bigger fear than state-level actors coming after you for your Nostr notes or toots or whatever.) Whether you think that's a good or necessary thing probably tracks very closely with your beliefs about whether money and its expenditure is protected speech. Obviously that's something about which the highest courts and legislative bodies in the USA already have complex and sometimes-contradictory views, so I certainly won't claim there's a single correct answer...even if my personal beliefs fall very much on the "money is a modern social fiction in no way connected to fundamental human rights" side of the spectrum.
