As long as Lucas is taking my money, he's entitled to my opinion. I and millions of other fans across the world have made him what he is today. He's a successful filmmaker because of us, and he's a billionaire because of us. I know he doesn't give a damn about my desire for the original cuts of the film to be on DVD, but since I am buying the "Special Editions" on DVD, I can criticize decisions that he makes that I do not agree with.
I knew the petition wasn't going to do any good because I believe Lucas' mind was made up a long time ago. No amount of begging or pleading was going to change that.
As a paying customer, I have a right to complain if the service is substandard. Stick that in your pipe and smoke it.
