This seems to radically mischaracterize the issues in that case.
"It turned out that keeping me on the team made my manager look good, and I overheard him boasting to the rest of the team that even though the rest of the teams were losing their women engineers left and right, he still had some on his team."

That's not the worst thing she reported, but it's there, and it's definitely very bad. Would you elaborate on what mischaracterization you see?
I bet there are a LOT of unreported such cases.
Susan Fowler's case has less to do with race/gender than sexual harassment and abuse of power. I sure as hell would avoid working there if that kind of behavior goes unchecked.
So if it's not exactly 50%, what percentage is it? How can you even figure it out?
A lack of diversity is one of those things that you know when you see. But as numbers improve, we are going to run into the problem where we have no idea when to stop obsessing over the numbers.
It's why I feel that equality in opportunity is the more effective measure. Are people doing what they want to be doing with their lives?
Something like 99.9% of midwives in Ontario are female. Is there a diversity problem? If you find men that feel like they can't become midwives for some reason, then yes. But not because that ratio feels imbalanced.
It'd rather seem that the primary argument to 'diversity' should be 'getting more women to study the relevant things'.
Though: surveys show that women in tech see the #1 issue is 'lack of role models' - ergo - a degree of feedback here, but really ... I firmly believe that if 50% of Comp Sci grads were women, that roughly 50% of Google Engs would be female.
Caveat: in management positions there is a totally separate spate of issues.
Also - similar issues apply to ethnicity. Tech is about 30% Asian, and very few African Americans or Latinos, which is again commensurate with the pool of graduating talent. Again there are clearly feedback issues - nevertheless - one cannot ignore this white elephant.
In every institution I've ever been at, people talked about how to recruit more women, but in practice this meant grabbing the first woman who applied and using them as a prop to show how diverse they were. Professors have blatantly admitted to my female friends that they were being used for that purpose.
