There is nothing in the email to suggest that. Disagreeing with company policy doesn't mean that she was not a diligent worker doing the tasks she had been assigned to in good faith.
So far Google hasn't stated the thing she did exactly that led her to being fired, ie the actionable thing she did that would have to be produced if she took it to a tribunal or to court?
Yes. Her words, emphasis added, but probably not the exact words in the email she sent:
> I said here are the conditions. If you can meet them great I’ll take my name off this paper, if not then I can work on a last date. Then she sent an email to my direct reports saying she has accepted my resignation. So that is google for you folks. You saw it happen right here.

> What are the exact reasons Google stated for her dismissal?
She sent and email saying she'd resign.
> and would agree to a date of resignation that would give her working colleagues time to adjust or takeover her responsibilities or whatever if they couldn't agree.
She sent an inappropriately critical email to too wide of an audience. This isn't someone you give another two weeks of email access to.
I'll grant you that it's not 100% clear it's a "resignation," but in a way, it doesn't matter; neither she nor Google wanted to continue their relationship. Complain about Google all you want when you leave, but don't send an email threatening to resign and act surprised when you don't have a job any more.
