There already is a "Ministry of Truth", as you put it. The point of the article is that Facebook _already_ picks and chooses which shared items it promotes into your feed, so the news you get exposed to is already the product of human judgement. So, Facebook can't merely wash its hands of culpability in the propagation of fake news as the product of some "mathematically neutral algorithm". There's no such thing.

Not saying I agree 100%, but I think there's something there worth considering.
