Many year ago I signed a NDA/non-disparagement agreement as part of a severance package when I was fired from a startup for political reasons. I didn't want to sign it... but my family needed the money and I swallowed my pride. There was a lot of unethical stuff going on within the company in terms of fiducial responsibility to investors and BoD. The BoD eventually figured out what was going on and "cleaned house".
With OpenAI, I am concerned this is turning into huge power/money grab with little care for humanity... and "power tends to corrupt and absolute power corrupts absolutely".
