Media Matters for America has filed a lawsuit against X, Elon Musk's social media platform, in a San Francisco court. The nonprofit claims X is violating its own policy by pursuing lawsuits in Texas, Ireland, and Singapore, instead of San Francisco. The legal conflict began two years ago when X accused Media Matters of damaging its advertising relationships. Media Matters is now seeking damages for legal costs incurred and aims to prevent further litigation outside the U.S. This ongoing dispute follows a controversial antisemitism issue that led to advertiser withdrawals from X.
