Facebook CEO Zuckerberg says his personal data sold to others

Mark Zuckerberg Congress testimony

"When people upload their contact lists or address books to Facebook, we try to match that data with the contact information of other people on Facebook in order to generate friend recommendations", Facebook said in a post explaining how the contact data eventually got leaked.

The exchange came a day after Senator Gary Peters asked Zuckerberg the same question.

"When Zuckerberg and chief operating officer Sheryl Sandberg keep talking about users being in control, sure, that true", Ms Johnston said.

She said that "robust penalties" for breaches like Cambridge Analytica's could be put in place, even for "first-time violations". Due to the heavily influential hand FB has on its users and the world, Congress wanted answers from Zuckerberg about what he's doing to maintain users' privacy.

Just how much data does Facebook really have?

Facebook's co-founder Mark Zuckerberg testified to Congress on Tuesday (April 10) about his company's role in the giant data breach of its users.

The Indian government had sent notices to both the companies seeking detailed explanation on any possible misuse of profile data of Indians to influence their voting behaviour.


Facebook lets you control your data - that's the idea Mark Zuckerberg returned to over and over this week as he testified before U.S. lawmakers. "While I applaud some of the reforms that you are putting forward, the underlying issue here is your platform has become a mix of news, entertainment, social media that is up for manipulation - we've seen that with a foreign actor".

On Wednesday, Zuckerberg hedged when Rep. Jan Schakowsky, D-Ill., asked if Facebook would extend the European Union rules to the United States. It turns out that people mostly entrust their information to Microsoft, Lyft, Tesla, and Netflix which barely managed to generate any negative response.

Facebook also includes a note about its data collection in its user agreement, noting that it collects data on "the websites and apps you visit, your use of our services on those websites and apps, as well as information the developer or publisher of the app or website provides to you or us". (For a primer on that, see this Gizmodo article.) Later, Ben Lujan, a Democrat from New Mexico, pointed out that "people who don't even have an account have to sign up for an account" to find out what data is held about them.

During the hearing, Mark stressed that Facebook had a counterterrorism team - with 200 members - who were focused just on fighting terrorism on the platform.

"One of my greatest regrets in running the company is that we were slow in identifying the Russian information operations in 2016", he said.

"You can use Pixels to measure all kinds of activity on a site", says Joey Muller, a partner at Sum Digital, a digital advertising agency based in San Francisco.

The 33-year-old CEO said Facebook was in a constant struggle to guard against Russian manipulation of the Facebook platform to influence elections in the United States and elsewhere. It's "Pretty obvious to me someone is listening to the audio on our phones", said the congressman.
