I'm really not interested in your data specifically as what happens if everyone follows you down this path (we’ve had this conversation before and agreed to disagree on this inr). But IMO, just to entertain this argument, we can take this line of thought to the extreme.
I have no illusion that AES-256 encryption is truly private against folks with the right resources. But going down that path, are you 100% sure that a relay running on your mobile is private?
Take this to the extreme and we’ll end up with non-social, 100% offline, share-nothing "social media".
At some point, you have to decide on features vs threat model. I’m happy to expose my social graph if it helps other folks discover good content on Nostr.
