The relay doesn't own the content though

There’s a quote from Dune: > The Power to Destroy a Thing is the Absolute Control Over It You can’t say that you own the content if you can’t delete it. When you hand it over the relays, it’s theirs more than it’s yours.

True but in the digital realm everything is just information and can be infinitely copied.

Not every protocol is like that. Nostr just has the perfect storm of no deniability and no delete

If you send information, it is copied, and you can't take it back.

You can if the relay’s delete it. It’s up to them to decide if they want to do that. It’s theirs to decide
