AFAIK NNTP has always fallen under the banner of p2p.
And thats where the debate was. Technically NNTP is not p2p. People (as was done in this thread), misuse the term. For a lot of people, p2p is synonymous with file sharing. However, technically its a specific type of file sharing. News servers are not peer to peer, they are server to client technologies.
When the term was first used in this thread, it was meant to imply "file sharing". A couple of geek debates later on the technicalities and this was changed to avoid the confusion ambroseg1 is currently experiencing.
