I'm not sure OpenAI compares to Enron or FTX in terms of unethical behaviour or financial fraud. The only similarities might be, funnily enough, disfunctional boards (or in FTX's case, no board).
Even if they're "just another tech firm", that's still enough for them to be another Facebook with the Cambridge Analytica and Rohingya scandals, and many people would like to make sure such things don't repeat.
Especially with all of the people leaving and publicly criticising the companies trust and safety stance.
