One difficulty with this line of argument is that there are a lot of things that are profitable but demonstrably bad for people. For example, should Ford and VW be required to place ads pointing out that their cars kill more people than anything else, and that their engines are wasting a non-renewable resource, and that they are the main contributor to greenhouse gases? And should sugar companies be required to point out that eating their product is bad for everybody not in danger of starving?
