As far as I understood he says google has a positive discrimination policy to hire minorities and want to achieve a 50/50 gender diversity (or at least something that doesn't match the diversity in the pool of candidates). That was my conclusion from sentences like this from the document:

- "Stop restricting programs and classes to certain genders or races."

- "Differences in distributions of traits between men and women may in part explain why we don’t have 50% representation of women in tech and leadership."

- "I’m also not saying that we should restrict people to certain gender roles; I’m advocating for quite the opposite: treat people as individuals, not as just another member of their group (tribalism)."

If this is not the case he should apologize for it.

Note: I mostly agree with his arguments.
