He didn't. The only one who was (literally) ostracized was Damore.
>consequences of openly questioning corporate policies.
Well, the policy was (supposedly) that you could in fact question corporate policies. Of course 'everyone knew' that it was bullshit, but at least now it's been proven and thrown into public for all to see.
I'm fine with a company not wanting openness, less so with such a company pretending to want openness. If Google subscribes to modern-day Lysenkoism (because they think it'll get them more profit) then that is their right, but at least quit the whole pretense and be honest about it: "Our company is about making money, not truth, not justice, not the betterment of society, but money, money, money."
But of course, that gets you less starry-eyed young minds than the "Don't be Evil" of yesteryear, so it's understandable they keep the mask on. Corporations are sociopaths.
