Internet “power user” Mark Zuckerberg knows Facebook has issues

Facebook’s CEO talks about how he’s fixing the world’s biggest social network as it reels from a massive data scandal.

In the wake of a scandal involving the improper sharing of millions of people’s data, Facebook CEO Mark Zuckerberg said Wednesday that the company realizes it has a broader responsibility for protecting its billions of users—though he also acknowledged it will take a couple more years to fix the problems.

Zuckerberg made the remarks during an hour-long question-and-answer conference call with journalists. It was held just hours after Facebook disclosed in a blog post that 87 million people’s information might have been shared with Cambridge Analytica, a data broker involved in the 2016 Trump presidential campaign. Last month Cambridge Analytica was suspended by Facebook after the Observer and the New York Times reported that the firm had access to user data it shouldn’t have had. Facebook’s post also said that starting April 9 it will let users know if their information may have been shared with the company.

During the call, Zuckerberg talked about how the company is trying to improve the ways it safeguards users’ data—something he says has been going on for the past year and is likely to take another two years. He noted that while Facebook already has privacy tools available for its users, the company is trying to take a broader view of its responsibility to protect them from those who may want to abuse their personal data or manipulate the platform to get greater distribution for fake news or hate speech.
