That article had an interesting point of view. I think George watches these movies a lot, and since he has the money, and the rights, he uses Star Wars to stave off boredom.
I don't believe the reasons he gives for implementing changes anymore. I don't think the low technology of the 70's and 80's has much to do with it at all. If that were the case, he would have stopped making changes after the "Special Edition" came out. Instead, he is still adding new voices, and sounds, with each new edition, all of which he was capable of doing decades ago without the need to go back and add them every 5 years.
The most comical, and perhaps disturbing, part of the whole thing, is that the more tinkering that is done with these films, the more they resemble this...
I remember when I saw the first knock off lightsaber in this show. I thought there was no way George would let them get away with it. For a long time it seemed like he would do nothing. But now I think he's may just be striving to get back at them, by copying their brand of movie making?
Being that the stormtrooper banging his head was such a silly thing to have, it would probably go along with the new versions too well to be edited out.
