"That is why regulating profiling is perhaps one of the most pressing privacy issue of our time", the group concluded.
Zuckerberg clearly admitted to mistakes and took responsibility.
Rob LeverFacebook founder Mark Zuckerberg emerged largely unscathed Wednesday from two days of high-stakes hearings that saw United States lawmakers grill the billionaire over how the online giant feeds users' data to advertisers and chide him over privacy rights. A day earlier Zuckerberg batted away often-aggressive questioning from members of the Senate Judiciary and Commerce committees who accused him of failing to protect the personal information of millions of Americans from Russians intent on upsetting the US election.
Seemingly unimpressed, Republican Sen.
"What we saw at these hearings is that he is resisting changing the business model of Facebook, which is based entirely on harvesting user data and taking that data and use that data to help target ads", David McCabe, a tech reporter with Axios, told Al Jazeera. Silicon Valley wants to make sure young companies get the same chance Facebook has had to put their data to use.
And that's how Zuckerberg described it a few times in his two days of testimony.
The Congressional hearings come almost a month after news broke that Cambridge Analytica, a data firm with ties to President Donald Trump's campaign, accessed information from as many as 87 million Facebook users without their knowledge.
Zuckerberg responded saying: "Congressman, that is an accurate description of the prank website I made when I was a sophomore".
And he argues people essentially choose to be tracked like this because they generally prefer targeted ads over irrelevant ads, and they keep the ad settings and opt in by signing into Facebook in the first place. He offered no details, citing a concern about confidentiality rules of the investigation. Stressing that there is an online propaganda "arms race" with Russian Federation and it was important to make sure no one interferes in any more elections including in India, Zuckerberg told Congress that his own personal data was "improperly shared". A number of the Russian ads were on Facebook. On top of regular accounts, many users created what is called a "finsta", or "fake Instagram". About 270,000 Facebook users shared the data with "thisisyourdigitallife" and this also gave the app information about the friend network of those people, meaning the data of about 50 million users was compromised.
Edwards said earlier this week 63,724 people in New Zealand may have been caught up in the data breach.
The company does this by using different techniques integrated into pages around the web.
Zuckerberg was asked to talk to the US Congress and he accepted the invitation. Lindsey Graham (R-S.C.) asked him if Facebook had any competitors.
"I think he's sorry he has to testify in front of Congress", Kelly said.
"I've just seen it over and over again - that we have the hearings, and nothing happens", Pallone said. Even former USA president Barack Obama's campaign made one that accessed the friend lists of those who used it. The scary part? Facebook acknowledged the abuse and released an official statement: "Given the scale and sophistication of the activity we've seen, we believe most people on Facebook could have had their public profile scraped".
