My bad for the previously missing source that's on me. Ive expanded on the thought below with references. (and despite calling me out you still can't find a single source for your claims (short of a vague, go read a document I clearly haven't read for me, which is just, beautiful))

Edited previous comment for the missing source, that's my bad. (and despite calling me out you still can't find a single source for your claims (short of a vague command to go read a document you clearly haven't read, which is just, beautiful))

Let's even abandon, for the sake of argument, any desire to see ratios in engineering even approach demographic ratios and instead just look at the rates graduating with CS degrees. That puts the ceiling closer to between 30 and 40 percent[0, for a representative top tier school] and, by your own admission, we close to half that on average (the numbers fall of faster if you consider technology leadership[1] or look more at smaller companies (which is harder to source considering a lot of places aren't very open with regards to their hiring stats, but in my experience working in nyc I’ve only seen sub 10% (N=3). Sub 10% to me essentially none, since that can basically evaporate with normal engineering churn). If we were to assume there was a grand bias, you'd expect an over representation in relation to the rate graduating at the very least.

“Thing exists” does not imply “thing normal” or “thing ideal”[3]. That’s a common logical fallacy used to justify traditionalism in all forms. Also, as an aside, people are talking about inequality in the HR field, you’re just not paying attention to it (tldr it is weird that there are more women and even with the numerical advantage they’re still underrepresented in leadership which reflects in their comp) [2]. When we look at technology it’s especially strange because there is no clear mechanism (outside of social bias) that might explain why we’d see the ratios present. Despite what men on the internet like to believe there’s no evidence women that go into math or computer science are worse at it than men. Estrogen is great but it doesn’t change your ability to write code. Hell no mechanism to explain why the ratios are more skewed than medicine [5] or law[4] even.

As for women being “uncomfortable talking with you about this”, I’d suspect that has a lot to do with your fear of a nonexistent feminsit boogieman and repeated claims that they don’t deserve their jobs than any kind of conspiracy. Imposter syndrome acts across genders and this repeated narrative plays to a lot of people’s insecurities.

This was far more effort than you deserve, but, I can only hope one day the culture at some of these major tech companies start to change, if only so I don't have to hear think pieces about how hard it is to hire from people that auto exclude 50% of the population.
I can't imagine why women are uncomfortable talking you, a proud sexist that openly claims there's feminist propaganda involved in their hiring. I can't think of any reason short of shame of being involved in such an obvious conspiracy.
