Even your perplexity output admits that it’s not fully P2P like bittorrent. And if we count “partial P2P”, then activitypub would also count since even selective replication, is some amount of replication, and tbus “partial P2P” I wrote p2p at server level. Ofcourse it is not 100% p2p, if it was full p2p then it would be just p2p. usenet is p2p at server level, and you have the references above to prove it (you don’t need to trust me).
