Yes indeed.  Nostr is still better than the status quo, because 3-4 relays is better than one central server.  But you cant compare 3-4 relays with 3-4 million nodes.  I have always considered nostr resilient like RAID, but the censorship-resistance is over hyped.  If you want censorship resistance we now have a bullet proof way with millions of nodes, and decades long track record.  Solution is to let nostr be nostr, and use the right tool for the right job.
