The point is that she shouldn't need to point out individual contributions by women. Because you'd hopefully understand that women don't go out of the way and say "hey, btw, I'm a girl!". So you'd understand technical articles by women are plenty, but they're not immediately obvious. Because women are not trying to make it immediately obvious. Because the internet is supposed to be gender neutral.

And hopefully, if you understand all that, you won't ask be asking "where are the technical contributions from women?" in the first place. So the question is mute, which is why she didn't answer.
