In my opinion, she is being very unfair to a lot of her colleagues by not telling the whole truth and at the same time making very serious accusations. She sent email to large group of employees which violated some standards expected from a manager by Google. She is giving all the information except for what exactly she did. It's ironic that she is in "ethics business" but at the same time not realizing that it's unethical to withhold what she did while launching attacks on everyone.
