He made money, but he was not primarily an entrepreneur. He ran a publishing house to feed himself and then was able to turn its management over to his partner so he could focus on furthering the enlightenment. If he were really an entrepreneur he would have kept a monopoly on the franklin stove, or bifocals, or any number of his inventions.
This is alike to saying Paul Graham is not primarily an entrepreneur, he made money to feed himself and later sold it to focus on furthering his ideas of a second enlightenment.
