Ethics is the study of what you can get away with. University level ethics people doesn't make people a whit better than they were already.
So maybe it's best this way. Computer scientists will still do bad stuff, but at least they'll be embarrassed about it when caught, rather than come up with clever justifications.
That’s not how the ethics class I took in college worked. It reminded us to feel empowered to speak up rather than build something we didn’t think was right, and what the best means of doing so were.
