There are major ethical and legal issues arising from the revelation that Cambridge Analytica manipulated Facebook user information.
But they pale against the big issue. The biggest revelation is the massive deception: that this firm was funded by Mercer; that Steve Bannon was the middle-man in that transaction; that this firm did not legally obtain the data; and that this psychology professor had a special relationship with Facebook that gave his ‘thisismydigitallife’ app access to not just an individual’s data, but the data of all their friends as well.
Facebook found out about this relationship years ago, told CA to delete the data, didn’t check that had happened, didn’t inform Facebook users, and there wasn’t enough done to make users aware that some apps have the ability to access the friends of an individual’s data.
Below is a video from as far back as September 2016, where Alexander Nix, CEO of Cambridge Analytica, provides a brief insight into how the firm manipulated the data to help Ted Cruz in the 2016 US Presidential election.
Of the two candidates left in this election, one of them is using these technologies; and it's going to be very interesting to see how they impact on the next seven weeks.Alexander Nix, CEO, Cambridge Analytica (September 2016)
