Education is valuable, money is (among other things) a token of exchange for value… Getting a good value for your time and tokens of value is a great plan.
Getting a good value for producing educational materials is hopefully not a primary incentive. But it is not an insignificant incentive.
I do acknowledge that it is a corrupting influence. One of my professors admitted in class that he revised his textbook every two years because the value of used copies of textbooks stayed too high for him feel like the investment effort of writing it paid off, compared to the costs of revising it, and pushing the new version as the text in similar classes in other universities. (He apparently is prudently ethically prohibited from making a profit by requiring it in his own classes.)
I find this article bewildering, but intriguing.
