Elon Musk adds Microsoft as defendant in his lawsuit against OpenAI

Elon Musk has amended his lawsuit against OpenAI, adding more anti-trust claims against the company and including Microsoft as a defendant. He also added his company, xAI, as well as Shivon Zilis, a former OpenAI board member and mother to three of his children, as plaintiffs. Musk originally sued OpenAI in March, accusing founders Sam Altman and Greg Brockman of violating the organization's non-profit mission by teaming up with Microsoft. He withdrew the state court lawsuit in June before suing OpenAI and Altman again in federal court. Musk was one OpenAI's earliest backers, and one of his arguments was that he was "betrayed by Mr. Altman and his accomplices."
