That's my reading as well. He tries to distinguish between "women can't be technologists" and "women can be technologists if they want to, but they don't generally want to".
I'm honestly not sure how one could in good faith make that case given the current climate. A couple weeks ago, I would have bet on his memo being generally derided but not anathematized.
> "I'm simply stating that the distribution of preferences and abilities of men and women differ in part due to biological causes and that these differences may explain why we don’t see equal representation of women in tech and leadership."
He also mentions this in one of his interviews [1].
