Actually, if you look, the original source said that Facebook admitted that they were only doing so because they wanted Obama to win - and that for anyone else it would be a violation of their practices. The OFA postulated that Facebook did the same for other parties, but no evidence has come to light.

In fact, reading what the OFA admitted, and what is under investigation here, the only difference seems to be that Facebook didn't unofficially bless the efforts of Cambridge, while they did for OFA.

Here is the money quote - directly from Twitter:

“They came to office in the days following election recruiting & were very candid that they allowed us to do things they wouldn’t have allowed someone else to do because they were on our side"

That's not a conspiracy theory, or some evil double standard. That is a director for OFA explicitly mentioning that they were being given special data "because they were on our side".

You should be very very scared about social network deciding to be on peoples side. See Trump and Twitter.

It's as if the last two years hasn't convinced you to be deeply skeptical of social networks and surveillance as a service operations. This universal confirmation bias is the exact same bias that Trumpkins use to ignore any news they don't like. Facebook will keep selling you to the highest bidder. They don't give a fsck about your political point of views.

(And this is probably tame for what they do for China to suppress their people).
