This is just how people work.
Notably real business acumen precludes lawbreaking, but until there is concrete evidence, I won't simply rely on the court of public opinion.
Otherwise I don't care if this old man has sex, I don't even like thinking about it. But he was reckless and up his own ass about it. And while I don't think that the chips are the gold they're made out to be, and completely don't buy the reasoning of how A. Huang's business would be in the service of Chinese "spying," she's certainly someone who could and would talk business with him. She may have been an advisor on the financial house of cards for all we know, and the Chinese would definitely be interested in destroying the US economy.
Hell, the covert Chinese action might have been to take a woman who is extremely suspicious, get her to sleep with Huang, publicly out the affair, and let the company fall into the hands of somebody who is going to do something very stupid with it. That would still be Huang's fault. Maybe, none of this has anything to do with the Chinese at all, and the Israelis financed A. Huang's company (which was also evading Chinese enforcement) in return for her seducing a known sexually incontinent J. Huang, they publicized it, and with J. Huang's ouster the firm will fall under Israeli control. That would also be Huang's fault.
None of this excessively involves lawbreaking or morality, just stupidity and incompetence. Which is not "business acumen."
Video game people are like sports fans, they fall in love with the producers of their entertainment and have parasocial relationships with them. I imagine that a lot of people who work at Nvidia now had that same relationship with the company as children.
You could have the exact same situation with a different company/CEO and the HN comments would be completely different
