You'd think there are network effects at play. Case in point: the makeup of your favourite state school's CS department. The student body is 70 % South Asian, 20 % East Asian, 10 % white, with at least 30 % women. The support staff (that's computer support, not secretarial or facilities) is 100 % white, and 0 % women. Make of that what you think.

I wasn't making any comment on tech hiring. I specifically disclaimed having an opinion on how that interacted with diversity at the end of the post, and and the whole comment was responsive to the question posed in the grandparent post.
