She went public with concrete names and bad things that happened to her while working at Google, regarding both an engineering manager Rod Chavez, and a VP, Vic Gondotra. While there were a few of the expected "where's the proof" people on Twitter, as Kelly said, the large majority of responses she got were supportive, from lots of men and women.
In addition, in the google+ thread, several people from inside Google expressed shock (they only heard about it now, it wasn't common knowledge across the company) and mentioned that a lot of noise is going on internally right now about this.
Gondotra isn't still with Google, but Chavez is. I would bet that won't be for long.
Overall, the responses internally at Google were horrible, back then. HR tried to save the company from liability, not help her. But when she went public now, the responses were good, and change might actually happen.
As the saying goes, sunlight is the best disinfectant. The article here is correct to say that it's scary to be a whistleblower, but Kelly Ellis shows it's possible to be brave, and that the industry and community will in fact react positively when you do.
