Firms including Apple, Disney, IBM and Comcast have paused adverts on X since the watchdog released its analysis. Elon Musk’s social media platform X has sued a left-leaning pressure group that accused the site of allowing antisemitic posts next to advertising. After Mr Musk threatened the lawsuit, Media Matters called him a bully. The advocacy group said last week that ads had appeared on X alongside posts supporting Nazism, such as Hitler quotes and Holocaust denial. The lawsuit, filed in Texas on Monday, argues: “Media Matters knowingly and maliciously manufactured side-by-side images depicting advertisers’ posts on X Corp’s social media platform beside Neo-Nazi and white-nationalist fringe content and then portrayed these manufactured images as if they were what typical X users experience on the platform. Do you think that the Jewish billionaires have ganged up against anyone who is not supporting Israel actions against Hamas?
