How to find out if Facebook shared your data with Cambridge Analytica


In prepared testimony released Monday by the House Energy and Commerce Committee, Zuckerberg apologizes for fake news, hate speech, a lack of data privacy and Russian social media interference in the 2016 elections.

For anyone wondering about Zuckerberg's possible political ambitions, Tuesday's hearing will be an opportunity to see how he handles the spotlight.

Last month, Facebook CEO Mark Zuckerberg promised to "show everyone a tool at the top of your News Feed with the apps you've used and an easy way to revoke those apps' permissions to your data".

"We didn't take a broad enough view of our responsibility, and that was a big mistake", Zuckerberg's statement says.

"For conservatives like me", Eric Wilson, Marco Rubio's 2016 presidential campaign digital director and founder of, recently wrote in a Politico op-ed, "it's not easy to call for increased regulation and antitrust enforcement, but Facebook has shown time and again that its leaders, including Mark Zuckerberg himself, aren't capable of responsibly wielding their vast power and influence in Americans' lives".

Facebook says most of the affected users (more than 70 million) are in the US, though there are over a million each in the Philippines, Indonesia and the United Kingdom. "We did this because the website may have misused some of your Facebook information by sharing it with a company called Cambridge Analytica", it reads.

"There are going to be people who are going to say Facebook ought to be broken up", Sen. That reach-through mechanism, under earlier Facebook policies, had allowed researcher Aleksandr Kogan to tap into millions of profiles by offering a personality quiz to about 300,000 people, who may not have been aware that they were exposing the data of their friends. According to Zuckerberg, the committee would work with U.S. foundations and a committee of academic experts to come up with research topics and select independent researchers to study them.

"My top priority has always been our social mission of connecting people, building community and bringing the world closer together", Zuckerberg states, "Advertisers and developers will never take priority over that as long as I'm running Facebook". A public apology by Facebook chief Mark Zuckerberg failed on March 22, 2018. Previous year third-party advertising on its platforms, including Instagram and WhatsApp, accounted for 98 per cent of its US$40.6 billion (NZ$55.6b) revenue, Facebook said in its 2018 annual report.

Facebook suspended B.C. -based technology firm AggregateIQ, which has been linked to the Facebook privacy controversy by Canadian whistle-blower Christopher Wylie.

Here are five questions that could shed more light on Facebook's privacy practices and the degree to which it is really sorry about playing fast and loose with user data - or just because its practices have drawn the spotlight. "One is the privacy issue and the other is the propagandist issue", he said. "The consent decree was designed exactly to avoid this Cambridge Analytica problem".

"And Facebook keeps saying its an idealistic company". That would add up to billions or trillions of dollars if multiplied by some or all of the 87 million users whose data was mishandled.

"We're in the process of investigating every app that had access to a large amount of information before we locked down our platform in 2014", said Zuckerberg.

Facebook has been scrambling to win back user trust since the scandal erupted, announcing that it would implement changes like labeling political ads and verifying pages with many followers.

At the same time Facebook is bolstering its lobbying capabilities.

Facebook compiles a wealth of information about each user. "Its about protecting our public sphere", he said.
