Zuckerberg admits it was a mistake not to ban Cambridge Analytica’s ads

Facebook didn’t ban Cambridge Analytica when it found out in 2015 that it had received user data from Dr. Aleksandr Kogan, and Zuckerberg called that a mistake during his testimony before the Senate. Cambridge Analytica has since been banned.

Zuckerberg explained that “I want to correct one thing that I said earlier in response to question from Senator Leahy. He had asked why we didn’t ban Cambridge Analytica at the time when we learned of them in 2015. And I answered that what my understanding was was that they were not on the platform, were not an app developer or advertiser. When I went back and met with my team afterwards, they let me know that Cambridge Analytica acutally did start as an advertisers later in 2015, so we could have in theory banned them back then and made a mistake by not doing so.”
