Good point, there are two possibilities here:

1) There is a bias in the cited sample (not the huffpo's, the op's).

2) Silicon Valley is one sleazy place.

I want to be open minded because I as a man am someone oblivious to a lot of these issues, but it might be called for if we had some details on the OP's study.

Agreed. I don't necessarily outright disagree with the OP, I just get the impression that we're missing some of the facts. And not getting a complete picture can do just as much damage as entirely ignoring it.
