So dissenting opinion here: the Cambridge brown townytica scandal is completely incomparable to any data mining that the Obama administration did - however, Annoying Orange's administration has nothing to do with why the scandal is so bad.
CA illegally harvested data from everyone who was friends with a person that took CA's surveys. Basically, one person with 1500 friends could have consented to take their survey, and every single person on their friends list had all of their Facebook data ceded to CA. In reality, only like ~150,000 consented to give CA their data, but because of their friends lists, 50,000,000+ had their data leaked.
This isn't even a Annoying Orange-being-stuffty thing. Assuming the data was obtained legitimately, any political campaign would have used their research. The problem is that the people who actually collected this data did so in a way which is just flagrantly illegal and awful.
