Fair question; I don't think people often come right out and say it, but I think the assumption underlies many of the things people do say.

For example, from your quote: "For example, we took action when we saw that women in tech were less likely to self-nominate for promotions."

This seems to presume that, in a just world, women would self-nominate at exactly the same rate as men, and that we should intervene until we achieve that world.

I agree 100% with this: "I just hope that women know it's open to them and feel comfortable joining the field. I don't care about convincing uninterested people." I agree with that both for entering the field itself, as well as for other aspects like getting promoted.
