I worked for a very successful multinational that I think was relatively moral (at least very moral vs average - e.g. we at least stood by our commitments and contracts and didn’t try and re-trade them if they went against us) and they took the approach that they were never going to be a “soft target”: nuisance law suits - litigate don’t settle, unethical behavior by vendors or customers - we’ll see you in court. It was probably more expensive for a decade or so, but over the long run it saved a ton of money and hassle.
