The ActivityPub standard and network exists. Nothing (absolutely nothing) is stopping the tabloid from running its own instance on nypost.com

edit: and I wanted to reply to a comment here referring to section 230 but their comment got flagged and I am unable to reply to them. Not really sure why it was flagged but whatever, HN does what it does.

My reply to that commenter would be that there is nothing stopping Congress-critters from standing up their own ActivityPub infra as well. A 'congress.gov' presence on the Fediverse would look pretty spiffy.
