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'.
(I'm basing this on the headline because the article is paywalled)
A product can be helpful to one person and harmful to another. Most products are like that. All sorts of things can be addictive to some people, from potato chips to video games.
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.
