This is not to mention that Facebook’s TOS have changed since the Obama 2012 tool. As anyone working with Facebook’s Graph API will know, the amount of data and filtering available to developers has been dramatically restricted in the last few years. This Cambridge Analytica approach seems to be a clear attempt to circumvent the spirit of the TOS and the ability of users to control their own privacy.

All you needed was one of your friends to play poker or take a quiz, and your personal information would be siphoned up by the app maker. It’s unclear whether the users who took part in the sham academic study paid for by Cambridge Analytica will be able to obtain any legal remedy, but it seems pretty clear that what they were being paid for was not taking a quiz, but rather for access to hundreds of their friends’ information.
