Are you deliberately trying not to understand? You clearly understand p2p technology, @Logen gave you a clear breakdown of what might be causing the differences, and yet you continue to repeat yourself without considering the points. My only charitable take here is that you are not aware that Nostr is p2p, in that case have a read here:

get nostr!

Come join us on Nostr, a new protocol for more than socializing

Even after understanding that if you expect Nostr to be exactly like Twitter or whatever else, it's really not for you. FWIW, I'll give you a follow because I generally liked when I saw your posts on Twitter.
