Elon Musk has filed a lawsuit to block OpenAI's shift to a for-profit model, claiming it violates its founding mission. OpenAI counters that Musk, who co-founded the organization and left in 2018, previously advocated for this model for personal financial gain. Musk's legal action includes accusations against Microsoft for influencing OpenAI's direction. OpenAI asserts Musk's claims are self-serving and disruptive, pointing to evidence of his earlier proposals for a for-profit structure.
