No one can censor you?

I don't think this is really true. Relays can censor your notes, or your npub - but you are free to use other relays, or your own relays. Content hosting (image hosting) can refuse to host your images or content. Anyone can ignore you, block you, or otherwise curate their content to not include your notes.

So everyone can censor you, individually. As it should be. The difference here is there is no central control over censorship. No one person or organization that can determine your content is not worthy of being transmitted through the nostr protocol. Each relay operator, content hoster, and user is able to censor for themselves.
