Seems to me that he thinks he's being fired for mentioning that grok 3 exists but he's actually being fired for saying that chatgpt is better than grok 3.
He’s also clear in his comments that xAI has the right to do whatever they want. He is giving more data points on how xAI/Twitter/Musk operate. This also doesn’t surprise anyone.
He might have misinterpreted what he was told. He might have been told multiple problems, and only reported one. He might be actively lying.
