His memo does not say "women are incapable of programming". He says the way Google uses engineers means men are more likely to fit the role. He offers suggestions on how to change the role to attract more women. For example, women may be attracted to social programming (pair or mob programming) versus the classic picture of some man locked away in a basement. Which he references specifically in the article.

This is different from discriminatory hiring of women to be forced into a male oriented role. This is a substantive claim, which he accuses Google of doing. Discriminatory hiring is illegal, and also stupid, from a free market standpoint.

Tldr: If women aren't buying your product (not applying to Google), it's not the fault of women, its your product that needs to change to suit their wants and needs.

This is only sexist if you think men and women don't, as a general statistical rule, tend toward different interests along a bimodal distribution. But they do.
