No, I merely think software houses reflect the gender makeup of the industry fairly accurately. Hell, I would be surprised if it turned out that that anywhere near half of software workers in general are women; this would imply that the majority of female software engineers work independently. I find that extremely unlikely, given how few women enroll in computer engineering degrees at universities. My point is that Microsoft, a mature and established software company, has a hard time finding female engineers, and this reflects the state of the industry as a whole.
