Mark Zuckerberg in court: Meta must defend itself against billion-dollar data protection lawsuit

A multi-billion dollar US lawsuit against Meta begins on Monday with the expected testimony of CEO Mark Zuckerberg (41). The plaintiffs accuse the parent company of Facebook and Instagram of operating an illegal online network because it allowed third parties to harvest users' data without their consent. The background to this is the Cambridge Analytica scandal that came to light in 2018. The political consulting firm used information from Facebook users for Donald Trump 's 2016 election campaign, which saw him win the US presidency for the first time.
