It glosses over it pretty quickly, but it sounds like he was charging a fee for frequency of checks for the classes. Part of the slide presentation shows that the school's policy surrounding their electronic services forbids commercial use or personal gain. Maybe that's part of the problem.

Edit: The conduct timeline makes this pretty cut and dried: http://ucouldfinish.com/conduct/ In the written statement of hearing determination (July 24, 2pm) they say specifically that he's in violation of their code by making unauthorized commercial use of their service. They then go on to talk about server loads, but the primary violation is the commercialization of their service.

He's also effectively selling preferred access to classes, which is something of an ethical issue.

And many universities handle waitlisting on a department or class level so they have leeway to deal with various factors as appropriate. Ever tried to implement university, departmental, program, and class policies simultaneously, while keeping them up-to-date, while handling who can override the computer under what amalgam of policies? No? Well, that's what you'd need to do in order to get automated waitlisting working at most universities.

The fact that there's not a university-level waitlisting feature isn't an excuse to hack around policy, especially not while violating ToS and misappropriating resources for commercial resale.
