Yeah, but what drives that perception? It doesn't seem to be rooted in any coherent theory of ethics. After all, users happily agreed to their data being used, they weren't forced to sign up to social networks en-masse, they weren't forced to install tons of crappy apps or agree to grant them permission to their friends data. They weren't denied any information or lied to. So the normal rules of ethics that would lead to conclusions about immoral behaviour don't apply here. Privacy isn't something that should be forced on someone. It's their life, their decisions, their information. They can do what they want with it. In reality virtually no users care about privacy and will happily upload their lives or even broadcast it to the whole world given the slightest chance. As such, it's hard to conclude what exactly Facebook employees are supposed to have done wrong here. That leaves "OMG YOU GOT TRUMP ELECTED", which isn't going to convince the roughly 50% of Americans who voted for him. After all, they won't believe that Trump voters were mindlessly reprogrammed into voting for Trump against their will by social media. And a lot of Clinton voters won't believe that either. I expect a whole lot of virtue signalling from the same Silicon Valley types who foam at the mouth if someone says there aren't many women coders because on average they choose to be teachers instead. And not much else.
