Elon Musk has threatened to sue media watchdog Media Matters and those who attacked his social media platform X, after large US companies halted advertising on the site due to antisemitic content. Musk endorsed an antisemitic post on X, drawing condemnation. Numerous companies suspended ads, including IBM, Disney, and Apple. Musk accused Media Matters of misrepresenting X's experience and undermining freedom of speech. Advertisers have left the site since Musk bought it, resulting in a rise in hate speech.
