So could you educate us by showing the comparable actions of the Obama campaign?

This Washington Post article has details. Obama Supporters clicked OK on apps, those apps pulled their friend graph (including the state of residence of friends) to generate outreach such as emails encouraging the supporter to evangelize specifically named friends on behalf of the campaign: https://www.washingtonpost.com/business/economy/facebooks-ru...

Didn't Obama's campaign hire Droga5 to do precisely the same sort of ad targeting that CA was involved in? Ultimately, it doesn't seem that CA did anything out of the norm for any marketing analytics company (from what I've read, correct me if I'm wrong).

Did you read the article? They paid several hundred thousand people via Mechanical Türk to download their poll app and then harvested 50M users data for political targeting.

Data they could have acquired directly from FB anyway? It seems like they found a way to make the data acquisition process more efficient (while also violating FB's TOS, which is the actual problem here).

But the point is, the methods CA used to influence voters weren't significantly different from Obama's 2012 campaign.

There is a giant difference here in the fact that the data acquired for CA was through a third party. Data obtained through the Obama campaign was through the Obama app.
