I agree that it's his business tinkering with his story. However, I also agree that he is no longer the sole owner of the original trilogy. I like the Leonardo analogy. If Leonardo, by some miracle of time travel, appeared now in the Twentieth Century and wanted to deface the Mona Lisa, would we let him? Hell no. We'd be like, uh-ah, oh no you don't...you crazy.
I think the whole oh, sorry, we destroyed the originals when we did the initial digitalization and modifications thing to them smells funny. Really? Screw property rights and all that. Please. When the original Star Wars became the cultural phenomenon that it did, then I think he seized to be the sole owner of them. For Goodness sake, the originals became a part the Joseph Campbell mythos! Anyway, all that fans of my generation ask is that the originals be made available. That is not too much to ask.
And what am I going on about, anyway? I don't even really care, I guess. The Star Wars universe/franchise peaked with Empire. There's no denying the power of, Luke...I am your father. Maybe he had the rights to ef with them they way he has, but yeah, it sucks what he's done to them. Take it back, George, take it back.
But at least Star Wars isn't the only game in town. Now us geeks have alternatives like the Harry Potter or the Lord of the Rings universes to embrace. I'm guessing J.K. Rowling won't be altering the Harry Potter films...as a positive contrast.
