If any relay chooses to censor you, you simply move to a different one, or host your own. If you backup the notes locally to your device, you can upload them back to any relay = the content is always yours.

I did not say, "Nostr is real censorship resistant." I said, "Nostr is building the right solution for real censorship-resistance." By "right," I mean permissionless and decentralized. By "building," I mean it's a work in progress.
