It needs to match the proportion of qualified women to qualified men, because to do otherwise is to either fail to employ qualified people or to employ unqualified people, both of which are bad for Facebook as a company (and arguably for the world at large).
I have not yet seen any concrete evidence to dispute the null hypothesis, that while gender is correlated with a great many things it is not correlated with the ability to be successful at Facebook. Therefore I accept the null hypothesis and think the right number is ~50%. I'm open to believing that the number should be different, possibly very different, given evidence.
