On Monday, Elon Musk’s X Corp, formerly known as Twitter, filed a lawsuit against an anti-hate speech group, accusing it of “intentionally and unlawfully” accessing the company’s data and conducting “a scare campaign to drive away advertisers from the X platform.” The complaint, filed in a California federal court, alleges that research conducted by the advocacy group Center for Countering Digital Hate (CCDH) cost the company “tens of millions of dollars.” The suit alleges that 16 unnamed advertisers either stopped spending on the platform, paused plans to advertise, or decided not to reactivate campaigns following CCDH’s research.
