It's not just that the grading was on a curve, it's that they learned nothing at all but still got a better grade than most of the class (implying that no one learned anything). Almost better to just have the whole class fail, then at least the department will notice that the professor is useless.

That wouldn't really be fair to the students who care about their GPAs, though.

You know it's the professor themselves that adjusts the grades? Of course the professor wouldn't fail the class if, as you suggest, it would make the professor look "useless".
