Elon Musk's lawsuit against OpenAI Co-founders Sam Altman and Greg Brockman, alleging they cheated Musk by changing OpenAI from 'non-profit' to 'for-profit', is set to begin on Tuesday (US time). "'Scam' Altman and Greg 'Stockman' stole a charity. Full stop," he said hours before the lawsuit. "I started [OpenAI]...recruited critical talent...for public good. Then they stole the charity," he noted.
