What I wrote didn’t make sense but it seems like you got what I was trying to say.
Fair point regarding the scope of information they have, and yeah, I can see some concern down the line.
I have to think through it some more and keeping an open mind, but the way I’m seeing it right now is if you’re using a public relay that you aren’t paying for then yeah, you’d run that risk. If it’s a paid relay and part of their ToS is not selling your information, then that’s the safer route for the end user.
Though I think for notes to proliferate you’d inevitably have to connect to at least 1 or more public relays that public goods.
