Walkie talkies replace guns. It's hardly on the same level as the Star Wars changes. There's no comparison. And no, unlike E.T., Star Wars was not available to consumers. And when it was made available, it was made available in an awful format - almost forcing you to accept the new revisionist Star Wars. E.T. wasn't anything like that. Spielberg has his cut, and the original cut. He recognizes the original cut and will continue to release it in future formats, and will not pretend it doesn't exist.
If you can't recognize the difference from that and Lucas, then I can't help you.
