The Betrayal of George Lucas

Why does George Lucas elicit such a sense of betrayal in Star Wars fans? For me, at least, it's the inexplicable sense of contempt he seems to hold for the fans of his work. How else could he try to push that bullshit about Greedo always having shot first? The petulance that anyone would dare question his "artistic vision," the self-absorption that doesn't seem to allow him to conceive that his "art" isn't just his anymore, that he gave it to the world and the world doesn't have to agree with him about it, the arrogant indulgence of whatever he happens to feel like doing today, because they're his toys, damnit: all of this is why we feel so hurt.
