I am also reasonably sure that FB (as well Google and others) are engaged in some pretty public efforts to improve the gender balance in tech. Or at least pay lip service to doing so. Might they be doing so because there actually is a pretty well known gender disbalance in tech.

Of course if you were meaning to say that a lot of negative moves on FB's part come from quite female Sheryl Sandberg, well, yes, but I don't think she's involved with the tech side.
