He's clearly not the best CEO for the company if his leadership has opened them up to a tonne of liability. The thing with Powell is problematic enough on its own, and yet it looks like a misdemeanor compared to the fact that he was sleeping with a Chinese spy and potentially knowingly sold chips to China in the face of a US-government-imposed ban. I just don't see why this is so hard. The best guy for the job is the one who doesn't risk the company and investor's money by overstepping into the geopolitical arena because he wants to poke some strange.
Given that a third woman (another coworker) has just been alleged, I'd say that Jensen was the best fit in a few other ways too. I'd be furious if I were an investor.
