Topic: Aleksandr Kogan

CBS's 60 Minutes interviewed Aleksandr Kogan, the researcher who collected Facebook data for Cambridge Analytica. Kogan explained that his app used a standard Facebook feature to access the data of tens of millions of users' friends without their explicit consent. He noted that tens of thousands of developers used this same "feature" for years, and that Facebook was fully aware of the capability.

A major revelation from the 60 Minutes report is that Aleksandr Kogan's research partner, Joseph Chancellor, is currently employed by Facebook. Kogan testified that he and Chancellor did everything together, yet only Kogan has been publicly discredited and financially ruined. Kogan also revealed that he consulted for Facebook in 2015, teaching them how to apply the lessons learned from the Cambridge Analytica dataset internally.
