As a counter to your story, I had one professor who required his students to purchase his own locally produced textbook, which had a new version with different exercises every semester or year, and I guess he made good money off of that because everybody thought he was an asshole for doing it, but he did it anyways.
I know someone who did that with his own book. Why? The publisher fucked him over in terms of pay. He even corrected a mistake in the original one.

Oh, name and shame for that shit.
Richard Burke at Casper College does this and doesn’t even use the book. Costed over $150.
Garbage practice that should be criminal fraud.
