I think this possibility doesn't receive enough attention, there is a class of people who've figured out that they can say the most scandalous things online and it's a net positive because it generates so much exposure. (As a lowly middle class employee you can't do this - you just get fired and go broke - but at a certain level of wealth and power you're immune from that.) It is the old PT Barnum principle, "They can say whatever they want about me as long as they spell my name right." Guys like Trump and Musk know exactly what they're doing. Why wouldn't Sam?
Johansson's complaint is starting to look a little shaky especially if you remove that "her" Tweet from the equation. I wouldn't put this past Altman at all, he knows exactly what happened and what didn't inside OpenAI, so maybe he knew she didn't have a case and decided to play Sociopathic 3D Chess with her (and beat her in one round)
