On Wednesday, Zuckerberg hedged when Rep. Jan Schakowsky, D-Ill., asked if Facebook would extend the European Union rules to the United States. And it's now a big enough thing that people now have to take this seriously. "It was my mistake and I'm sorry".
He said he was not familiar with so-called "shadow profiles," which media reports have described as collections of data about users that they have no knowledge of or control over. Here's what we did learn. The whistleblowing at Cambridge Analytica - a political data-mining firm that accessed the private information of millions of Facebook users to help target advertisements in support of Donald Trump during the 2016 presidential election - has brought to the surface numerous poor privacy practices the social network has engaged in over the years.
Protesters hold signs before Facebook's Mark Zuckerberg testifies at a joint hearing of the Senate Judiciary and Commerce Committees on the protection of user data on Capitol Hill in Washington, April 10, 2018.
"Our team made an enforcement error and we have already gotten in touch with them to reverse it", Zuckerberg told Congress. "We shouldn't have taken their word for it".
The company still isn't sure exactly how much personal data has been affected by third-party apps..
Rep. Joe Barton of Texas asked Zuckerberg why the social platform deemed the conservative content "unsafe".
"I received an email from Facebook that lists the people who have all invited me to join Facebook: my aunt, an old co-worker, a friend from elementary school, etc".
"Would you be comfortable sharing with us the name of the hotel you stayed in last night?"
Democratic senator Sheldon Whitehouse called out a problem with this plan, though: The legions of USA shell companies that hide their ultimate owner. "If you're logged into Facebook and visit a website with the Like button, your browser sends us information about your visit", Facebook's website says. Facebook confirmed to Wired that the app requested access to the inbox using the "read_mailbox" permission. "I think it is inevitable that there will need to be some regulation", he said. Again and again, people have claimed that they were served advertisements on Facebook on the basis of their real-life conversations, or on the basis a song they were listening or a movie they were watching.
Zuckerberg said, "For obvious reasons we do not allow people to turn off the measurement that we do around security". "That's the only way we can reach billions of people".
In 2015, Facebook was threatened with a 250,000 euro per day fine unless it stopped this sort of tracking against internet users who didn't even have Facebook accounts.
Back in 2010, a young Mark Zuckerberg told lawmakers that Facebook would always be free. 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.
