Facebook founder Mark Zuckerberg has broken his silence on the Cambridge Analytica scandal today in a Facebook post. Zuckerberg basically gave a timeline of events, starting at the creation of Facebook, leading up to the event. Zuckerberg states that "This was a breach of trust between Kogan, Cambridge Analytica and Facebook." Alleging that Cambridge Analytica got the data from a personality quiz app made by Aleksandr Kogan, and both Kogan and Cambridge Analytica were supposed to have deleted the data. Sounds like a lot of "it wasn't our fault" lip service to me. I understand that under their previous rules, apps could get user data from the friends of people who had installed it (why that was ever a "feature" remains a mystery), but even so, how does 300,000 people installing this quiz app equate to 50 million profiles? Zuckerberg will have an interview tonight on "Anderson Cooper 360" on CNN at 9PM ET. We have a responsibility to protect your data, and if we can't then we don't deserve to serve you. I've been working to understand exactly what happened and how to make sure this doesn't happen again. The good news is that the most important actions to prevent this from happening again today we have already taken years ago. But we also made mistakes, there's more to do, and we need to step up and do it.
