“We tried peace for two years, now it is war,” Elon Musk warned on X today alongside an announcement of the platform’s recently filed antitrust lawsuit.

X is suing a number of major advertisers for allegedly boycotting the platform following Musk’s acquisition in 2022. The lawsuit claims advertisers illegally banded together to discourage brands from giving advertising money to the social media platform, and CEO Linda Yaccarino has claimed today that the alleged boycott cost the company billions of dollars. Musk has been encouraging other companies to sue: “Everyone who has been boycotted should file a lawsuit in every country they’ve been boycotted.” Huge week for Big Tech lawsuits
