I would agree with you if George Lucas would be in a similar situation than the one you just described. Yet, as a matter of fact he owes his success to these 'imperfect' versions and he never seemed to care wether fans were happy with what they had. To take it one step further, it's not just a matter of disrespect towards the fans who'se devotion to StarWars helped him to get the possibility to do what he's able to do today, it's also a matter of disrespect towards all the participants in the StarWars project, which was a collaborative effort. George Lucas seems to think that he's a master at everything film, if he could he would eliminate all participants it takes to realize a film project. His ideal is some kind of holo-deck or magic wand as a tool to bring his vision to life without any other people "getting it wrong" and thus interfering with his ideas. The problem with this attitude is, that if it's so much about himself and not the dreams and whishes of others, that he should have kept all this stuff for himself. He may be happy about his situation, but he has forgotten that he's not the only person to be credited for his immense success.

Another thing I would like to point out is, that you had a very clear vision of how it should have been. That is not the case with George Lucas, imho. You just did what every OOT fan would probably have loved - took out the matte lines and some technical 'bugs'. You didn't think: "Hey, I think I'll put a rocket launcher in his hand instead of a guitar." He will never make up his mind how it actually should look and sound today or how some plot-nuances should be "updated". He can't even admit that the current DVD release of the classic trilogy is nothing more than a sloppy rush job, because the most important thing to him nowadays is the plot updates - not the film and sound quality. Slowly but surely he's dismantling all the quality standards in cinema and home video he pushed for all those years. Since the german DVD releases of Indiana Jones (german sound is merely stereo) and the classic StarWars trilogy (ruined ANH sound, inconsistent picture color and broken lightsabers throughout all three movies), THX has turned from a quality seal into a warning sign for me.

Nowadays it's just more about him and toy sale figures and less about a so called "definitive vision" or to retain certain quality standards.
