Dec 23 (Reuters) - Facebook owner Meta Platforms Inc (META.O) has agreed to pay $725 million to resolve a class-action lawsuit accusing the social media giant of allowing third parties, including Cambridge Analytica, to access users' personal information.The proposed settlement, which was disclosed in a court filing late on Thursday, would resolve a long-running lawsuit prompted by revelations in 2018 that Facebook had allowed the British political consulting firm Cambridge Analytica to access data of as many as 87 million users.Cambridge Analytica, now defunct, worked for Donald Trump's successful presidential campaign in 2016, and gained access to the personal information from millions of Facebook accounts for the purposes of voter profiling and targeting.Cambridge Analytica obtained that information without users' consent from a researcher who had been allowed by Facebook to deploy an app on its social media network that harvested data from millions of its users.The ensuing Cambridge Analytica scandal fueled government investigations into its privacy practices, lawsuits and a high-profile U.S. congressional hearing where Meta Chief Executive Mark Zuckerberg was grilled by lawmakers."
