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.
The person I'm replying to said "Ma Bell didn't collude with Russia to influence a presidential election and install a puppet president". They're implying that Facebook, in contract to Ma Bell, did do these thing.
In the context of an argument about why Facebook is a more dangerous monopoly than Ma Bell, this implies that Facebook did collude with Russia.
