I'm not sure if you read the same Wikipedia page I did. This isn't a turf war issue. A professor has been asked by editors to tell his students to stop editing Neuroscience/psychology articles because they are terrible edits that are unreferenced and plagiarized. This is bad because it opens up Wikipedia to liability. I haven't dug too much in but it seems like the Professor is brushing it off and refusing to really help that much which is why they are contemplating banning the entire schools IP range. It has to be really bad if they are even contemplating that point.
It's really not surprising that the professor reacted the way that he did. His intentions where basically to improve wikipedia articles in his field through a group effort by his students. Instead of praise and thanks from the wikipedia editors, he was ostracized and rejected. I'd wager this entire situation could have been averted if the editors initially reached out to the professor in a more positive way.
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.
>This professor started under the education programme in 2011. Following a study of edits made by the 2011 class here with commentary here[1], the professor was asked to stop and work with Wikipedia to fix the assignment. Instead he went underground and choose, in his words, to "fly under the radar".
