Within the context, it's clear to me, that the comment was not sexist. Can we write anything without 5 paragraphs of caveats and clarifications after every innocent sentence?

You’re reading too much into the comment imo - my read is that they’re simply responding to the title: “can it find a place for women?” “Yes, women are awesome in tech”

Basically they’re just supporting women in tech

It's worth pointing out that even by most "legitimately" gendered issues relating to careerism, tech caters pretty well to women's needs. A lot of women do, in fact, want to pursue motherhood, and tech is one of the easiest careers to stay involved in during the time-and-obligation demands thereof, rivaled only by a few other careers like writing.

There are many careers (ones that require you to travel, ones that require lots of in-person onsite availability) that genuinely are really tough for young mothers, and it forces a classic feminism catch-22 on them; namely, an unpleasant need to make a choice between seeking fulfillment via having a career, versus seeking personal fulfillment via motherhood. It's just really unfair that one has to choose and can't just do both.

As it turns out, there are a lot of careers where you can have both with no problem; but there are others that are a bad fit. (For an example of a career that fits this really poorly, take truck driving.)

Tech industry workforce is not a representative body. Normally we'd describe the situation as 'greater female participation in the industry'. The dissonance is reminiscent of Russell's conjugation:

https://en.wikipedia.org/wiki/Emotive_conjugation

Bertrand Russell, who expounded the concept in 1948 on the BBC Radio programme The Brains Trust, cited the examples:

I am firm, you are obstinate, he is a pig-headed fool.

I am righteously indignant, you are annoyed, he is making a fuss over nothing.

I have reconsidered the matter, you have changed your mind, he has gone back on his word.

None of these groups speak as one voice. People project meaning based on their own worldview.

A political group clearly stating their opinions is a different thing than people projecting meaning which was not intended.

Black lives matter the organization as much as one exists, has also had some fairly unsavory statements. I wouldn't necessarily attribute all of the beliefs of a group to each of its members.
