Facebook allows users to post links into a feed, how does that make them a news publisher?

OP didn’t say ‘break all contact’ any more than the government of the 5th largest world economy said ‘break all contact’ with the world’s second-or-third-largest-depending-on-how-you-count-it economy until and unless they give them a really good deal.

Also, Facebook and Google have regular severe problems with the government of China, whose economy about six times the size of the UK.

Sure, it would still be a drastic and childishly over-the-top response at this stage, but given the UK government essentially lobotomised itself a few years ago, it might happen anyway in more polite language.
