1. "Argues for biologically determined sex differences...
Not really. Argues that we can't rule out biologically influenced differences.
2. "fails to understand the current state of research "
Well, there's a whole bunch of researchers who disagree with that.
3. "argues cognitive sex differences influence performance"
Nope. Argues there are differences in preferences that come out at the population level.
3a) "in software engineering, but presents no supporting evidence"
Sort of true. It doesn't present evidence for performance differences, because it doesn't make that claim. It presents evidence for differences in preference, which is that it does claim
4. "fails to acknowledge ways in which sex differences violate the narrative of female inferiority;"
I don't even know what that is supposed to mean.
5. "assumes effective meritocracy"
Nope. See above about preference vs. ability. In fact, does quite the opposite, by assuming preferences and not abilities are often a stronger influence.
6. "makes repugnant attacks on compassion and empathy"
COMPLETELY WRONG. It references a plea for compassion instead of empathy, because empathy leads to bad outcomes, Against Empathy: The Case for Rational Compassion by Paul Bloom:
"Brilliantly argued, urgent and humane, AGAINST EMPATHY shows us that, when it comes to both major policy decisions and the choices we make in our everyday lives, limiting our impulse toward empathy is often the most compassionate choice we can make." -- https://www.goodreads.com/book/show/29100194-against-empathy
7. "contains hints of racism"Huh? Where?
8. "paradoxically insists that authoritarianism be treated as a valid moral dimension"
Huh? Where?
8a. "whilst firmly rejecting any diversity-motivated strategy that might remotely approach it"
Huh? He says that diversity programs at Google aren't working and he wants to replace them with ones that he thinks have a better chance of working.
9. "ultimately advocates rejecting all morality insofar as it might compromise the interests of a group."
Huh? He thinks the current programs are immoral and ineffective and makes a moral argument for replacing them.
So complete and utter BS.
And of course there are quite a few scientists who completely agree with him:

And more. And unlike here, they don't cite pop-sci books as evidence.
