The same critique could be leveled against anyone who "uses" a maid, plumber, doctor, actor, or cook.
When I make use of a cook, he really doesn't mean anything to me beyond satisfying my base need for food. I don't care about his feelings or the total complexity of who he is as a person. His only value to me is how well and how quickly he can make me a taco.
Does that make me an evil person? Is the cook somehow degraded or devalued by the job he does?
You're really stretching to make what isn't a credible point.
