In the original Dutch news report (linked to in the OP article), a third party lawyer observes that this was known about already but was not considered worthy of challenge. Recall again that the classes in question are aimed at lawyers; this is a very different situation than if they were teaching or consulting to copyright holders. Any legal class on copyright would also address matters like defenses to complaints of infringement and so forth.There's no reason to assume the class caters exclusively towards plaintiffs' attorneys.
All that said, I don't know anything about Dutch legal ethics in particular, and I might have misunderstood or mistranslated the information about the classes in question.
