Oh the paradox. Do you allow a company to keep your metadata and public notes private (which is an oxymoron in itself) or do you keep it all public and fair so there is at least no imbalance of power but now anyone can use your data? Because the opposite, to have everything private, is not a social or interconnected system and therefore is not useful to its users. So what is the solution? Tell people not to look? Yeah that'll work.

Nostr content and data is published to specific relays which constitute private communities.

So then just get those relays to gatekeep your data from Jack Dorsey... Whats the problem?

The problem will arise when the data is unlawfully copied/ingested from the relays.
