The service you seek is to gain knowledge and abilities. There is a body of evidence to suggest that you cannot gain that knowledge and experience without making considerable effort, and that the role of the instructors, be they professor or lowly TA, is to give you the opportunity. As such, getting easy-to-understand explanations, perfectly produced and complete notes, and attending entertaining lectures, is not the best way of achieving the stated goal.
Many lecturers are indeed less than ideal, and many instructors similarly fall short, but just because the students give them poor ratings, and complain about work loads, that does not mean that they are not being given exactly what is needed to achieve their stated goals.
You don't get physically fit by listening to work-out videos and watching people jog in the park. You have to go out and do it yourself. People hire personal trainers to devise a plan, and then to shout at them to make them stick to it and to put in the work.
Maybe that's a good analogy. Maybe to get good at math (and programming) you actually need to put in the work, and true learning is born from the effort and confusion you go through before enlightenment.
