"presumably to be replaced with younger white men similarly incapable of standing up to fascism"

Wow. Google, Microsoft, IBM, Intel, Micron, Nvidia all have Asian men incapable of standing up to fascism.

White CEOs appear to be the minority in tech companies.

Fascism is literally the union of corporations and the state. So why would a CEO stand up against it?

Only the people will stand up against fascism, in a mass movement for freedom and democracy.

It's not about their race. Plenty of Asian people in Silicon Valley. Or even their personal beliefs. It's about the interests of shareholders, which they have to (by law!) satify. That means making profit.
