Elon Musk's X is suing a group of advertisers. The lawsuit filed in a Texas federal court on Tuesday accuses the advertisers of unlawfully conspiring to boycott the social media platform. Advertisers expressed concern over changes Musk made when he purchased the platform formerly known as Twitter in 2022. X claims the Global Alliance for Responsible Media conspired with brands like CVS, Mars, and Unilever to "collectively withhold billions of dollars in advertising revenue" they owed to the platform.
