A Delaware court has opened proceedings in a major $8 billion class-action lawsuit targeting Meta CEO Mark Zuckerberg and other company executives over alleged violations of Facebook users' privacy linked to the notorious Cambridge Analytica scandal, according to U.S. media reports. The lawsuit, filed by Meta shareholders, claims the company failed to disclose critical risks of user data misuse by Cambridge Analytica, the political consulting firm that worked on Donald Trump's 2016 presidential campaign, News.Az reports, citing foreign media. Shareholders allege that Facebook (now Meta) violated a 2012 consent decree with the Federal Trade Commission (FTC) by continuing to collect and share personal data without user consent. According to the complaint Facebook sold user data to commercial partners and the platform removed key privacy disclosures required under the FTC agreement.
