I would agree, even from non-users, if someone sends me a link, I literally can't open it in most cases without creating a social credit score, I mean account...
While it's not directly the same as a proof of concept, I would point you towards BitChat. It has continually gained more global adoption and in the places it's needed, user retention is high. The people that had it once for a protest are keeping it because you never know when you might need it again.
In my opinion, Nostr is a lot like Bitcoin adoption. The places where it's needed it's adopted, which is proof of concept. And a lot of the places where convenience outweighs tyranny or the restrictions. but, especially with fourth-turning vibes around us, this could change quickly.
