I've thought about this and I think I agree with you about the amount of noise around tech rather than other careers. But what I don't want to do is jump to a conclusion about it, it seems like a nuanced question.
My mother made a left field comment a couple of years ago that I've thought about a lot. She was a programmer starting in the 70s through to the late 00s. I mentioned the lack of women in tech thing and she said "Oh. I've never noticed. I always considered it completely equal and never felt treated differently."
It's often mentioned about UK politicians too, ie the gender balance of cabinet positions.
Perhaps your view of the apparent moral urgency is because you're in the tech industry and therefore closer to it?
