For a large proportion of bullshit viral posts, the decision needn’t be that nuanced, and I’m not sure who’d be in a position to sue; Facebook writes its own laws as far as its platform is concerned.
As I have said before, any remotely non-toxic version of Facebook will have to take some kind of editorial position, if only “we won’t allow stuff that mainstream society would consider abominable”. That’s still more laissez-faire than any newspaper or TV station has ever been, and they’ve managed not to be burned down by angry mobs.
If their editorial voice turns out to be that of Fox News, good luck to them; they can keep the problematic, demographically unappealing fifth of their current user base, and someone else will provide a home for the larger and more attractive segment of the population who are sickened by that shit.
