I see the downvotes, but I still don't see how some guy self-publishing and printing his own book at Kinkos is proof for a conspiracy in which publishers collude with professors to force students to buy books from that publisher. If anything, it's an example for the exact opposite.
I'm not denying that black sheep exist, I am denying a pervasive conspiracy of "big textbook" to the benefit of the professors.
Also, an easy solution to not everyone buying Kinko-printed spiral bound lecture notes easily comes to mind...
