The data was subsequently given to Cambridge Analytica, in what Facebook has said was a violation of Kogan’s agreement to use the data solely for academic purposes. In his email to colleagues at Cambridge, Kogan said that he had created the Facebook app in 2013 for academic purposes, and used it for “a number of studies”. “We made clear the app was for commercial use – we never mentioned academic research nor the University of Cambridge,” Kogan wrote. These changes were all made on the Facebook app platform and thus they had full ability to review the nature of the app and raise issues. Whistleblower Christopher Wylie told the Observer that Facebook was aware of the volume of data being pulled by Kogan’s app.
