It means literally everything. I know the notes that I'm signing, making public, and posting to relays. That's the entire point. On closed platforms you have zero control over that process.

We’re not in disagreement …
All good. Just want to make sure passerbys understand there is a massive data sovereignty difference between close sourced, centralized platforms and Nostr. It's night and day.
People selling your public data farmed off nostr relays is not the same as what takes place on something like Gmail, Facebook, Instagram, TikTok.
You're in the driver seat on Nostr. On the others you're more like a doped up passenger in the backseat.
