This one actually took me a moment as well but my interpretation is that he's pointing out the gap between expectations and reality.
Or more specifically, privacy vs the illusion of privacy which is where the real danger lies.

Dont care about people recording me "forever" i only care about things that i can change. I already see that major relays keep all notes no delete forever, if what Odell say is that those relay are from those bureau with three letters.
In a privacy way people should be able to do what they want with "THEIR" notes/stuff.
