You cannot make changes while cutting off your own hands. The fact that Google made the step to try to change their AI practices by hiring her in the first place was a huge risk to them. Then all they ask was not to ruin the business and she went all nuclear option and ran to the press about it.

As I see it at this point, her inability to navigate the politics of the situation showed she was incapable of doing the job anyway. She should have been highlighting her presence and recruiting people that believed in the cause. Instead she upended the table and left the second there was some friction between her and business interests.
