This is very much like the gender imbalance in tech - starting to address it in college only provides a band-aid. This is a much deeper issue that starts soon after birth.

As a CMU grad student they had the Reasonable Person Principle to help guide your actions and interactions. The principle states nothing about ethics, but generally that you should be open to others' concerns, practice self-reflection, and even accept that their viewpoints differ from yours. In spite of this principle being in place I definitely dealt with at least one very unreasonable person during my graduate studies there.

I've been in several ethical conundrums in my career. In a couple cases my choice was the "lesser" unethical option among many. It can be difficult to make those choices when your career or employment is on the line. I've left jobs because I believed (or knew) the work I was doing wasn't quite on the level.

Trying to recreate these scenarios, realistically, in a class room is pretty hard. Having discussions about ethics is nice, but probably not very effective. Could you build a course, or assignment, where the only way to get an A is to cheat or act unethically? Would that even be ethical for the university to offer?

In my cynicism, this looks like a "cover-our-asses" maneuver by universities, at least in part.
