"Google has created several discriminatory practices: ... Hiring practices which can effectively lower the bar for “diversity” candidates by decreasing the false negative rate" [Mind you _lower the bar_ is a hyperlink, to a gdoc I don't have access to, so he's citing another document as evidence of this practice].
So he is in fact arguing a factual claim, that google has applied inconsistant standards in practice, as I suggested in my prior post.
