I don't necessarily believe he's a misogynist, but I do think he's in denial about the impact of sexism on gender gaps. To quote his letter:
"We need to stop assuming that gender gaps imply sexism."
The fact is that we don't have to assume. It's fairly unlikely such gaps are entirely the result of sexism. But to suggest that sexism does not play a role in gender gaps is absurd.
Edit: To respond to similar points in the replies, yes, I'm quite aware that you can read this sentence in the strictest logical sense as saying a gender gap, in and of itself, does not imply sexism. This is obviously and trivially true. But studies on evaluatory bias tell us that biases, such as and including sexism, are in fact the norm. It is so fantastically unlikely that they are not present among Google's interviewers / hiring committees that the sentence, taken in the strictest sense, is making an irrelevant point.
Rhetorically, however, it serves the effect of suggesting we ought to consider it plausible that perhaps sexism isn't at all at play in Google's hiring. Which, again, is absurd.[1] It would be far more likely that Google's hiring tilts sexist against men than sexism not being a factor at all.
[1] Note that this has nothing to do with Google specifically, but rather with humans generally.
