My professor is copying content from another class, should I do something?

The assignments were kind of strange so I searched an old assignment that we have already completed. Lo and behold, it is copied word for word from another class. So are the other assignments. There is no citation, and the professor is passing the work off as their own.

The course it is copied from is a free to lower cost course.

I am feeling quite upset about this since I could just take this cheaper class instead of paying the university rate. It also feels like plagiarism from the professor and low effort.

Should I report this? I feel upset with it all. This actually is the second time it happened at this university, though with another professor.

Or is this just common?

-edit- I am in the USA
