I think she is silly. I personally agree with her, but if the students are used to taking notes like that, then why deny them that? My husband is a professor and has learned not to do these stupid things when it aggrevates students. Many teachers ban cell phones, but he has a lot of adults with children taking his classes and doesn't want to deny them that. So he uses humor. When someone's cell phone goes off, he begins to dance to the music; it embarasses the students. Another teacher there has the student sing to the music for the class. You can do little things so that students get the idea. If these students think this is so important, let them do it.
You are correct in the sense that there are students taking notes on a laptop who literally know no other way to do so. In other words, they will be caught in this professor's net. On the other hand, as Prof. Lien argues in her law review article (and I have observed myself), in a class where the professor is relying on the Socratic Method, the system nearly grinds to a halt because half the students are too busy taking dictation to participate.
"You can do little things so that students get the idea"
Your husband is a good teacher.
I had a civics prof. who encouraged class particiaption and made like he was huffing on a joint every time he mentioned the term "~joint~ session of Congress".
It got to where he'd say "joint", motion the class to proceed and there'd be 60+ people acting like cheech and chong for about 5 seconds, then he'd continue "session of Congress".....
