I love when professors send you a list of sites you should stay away from lest you’ll get an illegitimate copy of the textbook. I love it even more when professors just don’t care about the optics and straight up email the whole class a link to libgen. But there was one professor at my uni that outdid all of them. He just took it upon himself to write a textbook for every course on the entire math curriculum and sold them for like $3-5 depending on the size of the book.
