This is really questionable practice, in my mind. They shouldn't be able to copyright something which they have questionably taken from somebody else. Printing materials in the way they are doing also goes against educational practices around accessibility

This part surprises me (that the university has allowed an individual lecturer to register copyrights). Educational institutions would usually have a blanket statement in their employment contracts stating who 'owns' the materials created for the purposes of work...

I think this is key. The case may be disputed, but everyone (probably?!) agrees that it is "ethically murky"

Is there any movement towards agreeing on its use/meaning?
