It's almost as if we've collectively forgotten the data breaches of the last 12 months and how exposed American and EU citizens are now to fraud because of lax security practices by credit scoring companies.
I guess the difference is that Facebook is actively sharing this data and Experian was hacked, because their breach was the action of an external agent, they are less culpable.
From the UK it looks like this. Trump used data, Facebook helped, politicians are upset that Trump was helped by the Facebook platform (conveniently forgetting that every campaign before that has used large amounts of Facebook user data), let's punish Facebook.
Facebook doesn't care about users, but politicians who have the power to change this care even less.
