I did not read the article, but I have been aware for forty years that Friedman's thesis that the primary goal of corporations is to make profits for their shareholders is a fallacy of the worst kind.
Smith said in essence: If you get up early in the morning to make "dough," you'll be useful to society and thus, allow to sell your bread for profit, the invisible hand of the market will control the amount of profit you can make. Profit was the means to incite people to be good for society.
Serving society was the antecedent and profit, the consequent.
Friedman fallaciously affirmed the consequent in his thesis by affirming that profit was the primary goal of corporations.
