Wearing a blue suit, a white mask, and glasses, Zuckerberg appeared in federal court in San Jose, California, to defend Meta's acquisition of virtual reality app developer Within. The FTC sued the Facebook and Instagram owner in July to stop the deal, saying its "campaign to conquer VR (virtual reality)" began in 2014 when it acquired Oculus, a VR headset manufacturer. It has accused Meta of trying to buy its way to dominance in the metaverse.
