I think that’s just not reliable. That’s a whole different issue than censorship resistance.
Nostr is censorship resistant because you can run your own relay and run your own client. If a relay or a client bans you, you're not gone or banned. You just pivot and you're back in business with little to zero downtime.
I don't see that as censorship resistant. Internet infrastructure the public paid for doesn't serve the public and telling members of the public they're on their own fixing it isn't magically an improvement. Nostr however has the potential in the future to bring infrastructure back to where it was at its peak and beyond, that will be censorship resistance
