So your "publicly" available data is aggregated and analyzed to help a campaign ( or any business for that matter) to make better decisions to achieve a desired goal or outcome? Ok since it was public data it is not a "hack". I think people are upset because of how inept and clueless they really are and the outcome that happened they did not particularly agree with. Oh btw this was happening before the last election and it is still happening to this day. If you step foot into the public realm, i.e. you utilize ANY sort of social media, email, etc., well then you have data points on you. So the term hack is completely out of context and I would advise people to read words in books to educate themselves on the actual meaning of things. This documentary is basically a cry baby rant about people feeling like they got duped. Newsflash you were not duped you are either just lazy or dumb or both.
