It's perfectly easy to frame ethics for the outcome you want depending on your a priori assumptions. 2) it's blatantly obvious that the business "needs" will supersede any ethical concerns or the ethics will be framed in a way that aligns with the primary goal of gaining money and power.
I don't see either of those as reasons not to train on it. Training isn't zero sum. You don't need to take something out to train ethics, and whether you explicitly train it or not, models will take ethical stances. Your second point actually argues in favor of training because that is still an ethical stance.
I think a lot of people confuse ethics training with "don't be evil"
