“Sam Altman’s YC HARC NDAs”, Sean McDirmid2024-05-17 (OA)⁠:

When YCR HARC folded [c. 2018?], Sam [Altman] had everyone sign a non-disclosure anti-disparagement NDA to keep their computer.

I thought it was odd, and the only reason I can even say this is that I bought the iMac I was using before the option became available. Still, I had nothing bad to disclose, so it would have saved me some money.
