OK, agreed - that was definitely unjustified hyperbole. By all accounts, they did not intentionally "collude" with the Russians.
But what looms larger in my mind is the fact that FB was egregiously negligent in allowing the manipulation of their platform to take place to the extent that it did --- both in the context of that fiasco, and in much worse situations, e.g. in regard to the genocide against the Rohingya in Myanmar.
