This is very interesting and I did not realise this would be an aspect to be considered when speaking about CC. Of course, looking back it does make sense.

I believe that the underlying intention of the project of sharing lectures is not problematic at all. Bottom line is that this is always promoted by lecturers, ask your peers for information first, then go to a tutor/professor for more information. This project creates a middle step, which is to check the notes available to students from other students, which will deliver a different explanation which might make the content clearer. This is common practice amongst students globally. However, where this case truly get murky (and moves away from my preference) is when it is sold to students. The sharing of knowledge SHOULD be free. It SHOULD be common practice for students to share knowledge freely. The reason why they are going around the copyright is so they do not have to pay, and then they turn around and sell the information they received for little to no money. This is where the project completely loses me. Good intentions, but very bad in practice. An organisation such as Studydrive is a free document sharing organisation, which is much more up my alley and has been incredibly helpful throughout my years of study by providing different perspectives on the lectures. However, I do believe that the lawsuit is defending their position of copyright with arguments that go beyond that which they wish to change. The stance of the professor is endangering the free sharing of knowledge by students world-wide and this will limit global knowledge and research sharing.

This will be an increasingly interesting topic in the following times post Covid19. Especially HEIs will have to make significant changes to their education system, likely following the direction of Open Education.

A great example of the benefit which a more open copyright (or copyleft) practice can bring is that previous data can be shared more easily, which leads to more research built on the previous knowledge. This enhances the global research community.
