That was from last year.
This year there was no notice because apparently he decided to not publicly announce he was doing it again this year and it took them some time before they realized what happened. It seemed that he didn't like the fact that people were pointing.
I can't read through everything so I may have not been following everything correctly. This is what I've extracted about the situation by gleaning information off the various pages talking about this.

My impression after perusing a fair bit of it is almost completely opposite of what you're claiming here.
What? How?
textbook copyright owner notices + sues wikipedia
This instance is a bit different. WP recognises the importance of student editors, even as part of student course work. There's an established program to welcome students and their teachers; to introduce WP to them; and to help them through the baffling bureaucracy.
This professor was invited to that program. They declined.
I know this is beating a dead horse, but I get really sick of hearing about abuse from Wikipedia editors who have gone power-mad. Edit-wars, blacklisting, and more is an ongoing state of affairs on the site. The fact that they are considering blocking the campus and a large chunk of the surrounding area from editing wikipedia in order to punish the professor is just stupid.
I understand that editors put a lot of time in cleaning up wikipedia, and that is great. But wikipedia is a system designed for public use, and that use includes editing and updating articles.
The problem that they have found themselves in now is that articles slowly evolve their own individual bias based on the managing editors point of view. New users and counter arguments are lost, as it's rare to find someone to edit an article that has the patience to start an edit war with a moderator who has babysat an article for years.
