If the relay is free, you are the product. You don't really control your data. You can be censored at any time. Not that different from Twitter.
Old saying, from a centralised paradigm. So if my brother runs a relay, am I his product…? No. Lots of family, and community relays, makes Nostr not be a twitter… New saying Lots of relays, not anyone’s product!
Wishful thinking.
