Mark Zuckerberg Grilled Over Facebook Privacy Promise as Jury Hears Testimony in New Mexico’s Second Trial Against Meta

Mark Zuckerberg was put on the spot over a promise he made about Facebook users’ personal data more than a decade ago, as a New Mexico jury heard his virtual testimony, KOB 4 reports.

The Meta founder was questioned about a 2010 Washington Post op-ed in which he assured users that Facebook “never shares your personal information with people or services.” Prosecutors pressed him on that claim after jurors saw an email from a Facebook executive acknowledging that the company did share personal data. Asked about the apparent contradiction, Zuckerberg called the issues “very nuanced points” in the deposition played for jurors and said Facebook had debated how to communicate its basic beliefs about data sharing.

The case is New Mexico’s second trial against Meta and traces back to the Cambridge Analytica controversy. It began with a personality quiz that exposed data linked to the Facebook accounts of people who took it and, under the platform’s rules at the time, information tied to some of their friends. That data ended up with Cambridge Analytica, a political consulting firm closely associated with data-driven targeting during the 2016 election.
