Because I'm a cynic, and because at the executive level this is how things work. I could equally ask you to justify your cynical view of "big tech companies".

Because I'm a cynic, and because at the executive level this is how things work. I could equally ask you to justify your cynical view of "big tech companies". But I won't because I'm perfectly fine working with your chosen bias. Especially since you were so up front about it. Personally, I'm no fan of Google either, and I accept this cynical view of them. But there's plenty of space for cynicism on both sides in this situation. She was pressing the nuclear option by threatening to resign, so I assume that the relationship was already strained. And I severely doubt that it was entirely over the one cited instance. Therefore, I doubt she's going public to try to win her job back. She could solely be trying to give Google a black eye on her way out, whether out of disgust or altruism. But doing so requires her to paint Google as "the bad guy", and that in turn requires her to paint herself as "the good guy". So net effect is the same, regardless of motivation.
