Low transparency filters are still a form of censorship. Sure, Nostr is unique in the fact that it allows you to choose your client and your relays. This is already way better than alternative microblogging platforms, which can take away users' ability to communicate even when they know exactly what's going on. However, Nostr's theoretical censorship resistance is kind of moot when there is no way for a user to figure out how to actually achieve it in practice. Which relays do you draw from? What client do you use? What settings should you change? One of the greatest aspects of the Fediverse is how so many instances publish blocklists that anyone can view. As I understand Minds, all of their moderation decisions are incredibly transparent. What can a new Nostr user do if they want to audit a relay that "only filters spammy notes"? How can a Noster user tell when they are missing a note? And how can a Nostr user find that note after they find out about it? New users already complain about how it's impossible to differentiate relays. And it's a general consensus that a user shouldn't have to read the source code of a client just to figure out what it's filtering by default.
