Well, with Lucas's ILM employees, I'm sure he payed them plenty for their hard work. Plus, he's acknowledged their work in the past. Now, I'm trying to sound like a smartass, but, I believe he just feels that he has the right to move on, and finish what he began. Those employees may or may not like his changes, we'll never know. When you hear them, they sound like they do but, of course, you can never tell for sure. I suppose he feels that they have served their time in the films, and now he can replace them. After all, he DID already release the originals, so both versions are available. Maybe not on DVD, but technically, he did release them. I think that's how he looks at it. You've heard his quote where he says if fans want the original versions they can go buy the laser discs? Well, that shows his opinion.
