What is a "moral" law as opposed to a "legal" one? If he is actively promoting a harmful product, I think that would fall into many people's definition of 'morally wrong'.

There was a major public campaign in the 1950s to ban rock & roll music, and in the 1980s to ban heavy metal. In each case, there were legions of "experts" calling those genres "harmful", and they were taken seriously -- congressional hearings were held, etc.
Point is, "promoting a harmful product" is very much in the eye of the beholder, and doesn't work as an objective moral standard.
