Nostr is literally the manifestation of a trustable privacy preserving tool, nothing like this exists for personal privacy, it is privacy without needing to trust, verifiable privacy,

Can you still be stupid on it, ofcourse. But no other tool allows you to be this private, while communicating publicly.

Saying nostr is not private is literally harmful to people who need privacy and now think that they have no other option than to trust a service that will eventually rug them.
