This was a fake scandal. "Democrats seem to like Harry Potter" is not some genius psychographic ad targeting strategy. The Cambridge Analytica people were selling snake oil

That said they did buy user data from a quiz app which is not really how you were supposed to use the Facebook Platform so that still wasn't really FB's fault I think

So the real issue was just people trying to blame the 2016 election (adverse to their interests if they were anti-Trump) on Zuck.

Heck to this day Ben Shapiro is one of the biggest podcasts and Tucker's show is even bigger than him so the right wing is a real force in American politics and not just propped up by FB's old newsfeed algo
