Elon Musk testified in a federal court in Oakland, California, that he is suing OpenAI and its co-founders, Sam Altman and Greg Brockman, over their controversial transition from a nonprofit to a for-profit organization. Musk argues that this shift undermines the charitable mission of OpenAI and sets a dangerous precedent for other nonprofits, stating, "It is not okay to steal a charity." The trial, which is expected to last three weeks, could have far-reaching implications for the future of charitable organizations in the United States. Musk's attorney claims that Altman and Brockman took advantage of Musk's contributions and guidance to establish OpenAI, only to later abandon its original mission for personal gain. The lawsuit also scrutinizes Microsoft's significant investment of $13 billion in OpenAI, which Musk's legal team alleges facilitated the betrayal of its nonprofit principles. OpenAI's current structure includes a nonprofit foundation overseeing its for-profit operations, with Musk seeking to reverse this change. The jury will hear from various witnesses and review extensive documentation before issuing an advisory verdict, which will inform the final ruling by U.S. District Judge Yvonne Gonzalez Rogers.
