Why are crutches bad?

Why are crutches bad? I’ve beat my stutter using Lee Lovetts method. I had recommended the book that helped me “how to stop stuttering and love speaking” to other people and they seemed turned off by crutches. That I don’t understand… why is it bad to try speak fluent? How is it cheating to avoid blocks? I’ve used crutches to get through blocks but now I don’t even feel the need to use them and can speak without stuttering anywhere no matter who it is
