Yeah in his mind it only applies to comporations or other people including the artists family changing their work posthumously. He supports artists who change their own work.
If the three stooges were alive and said they wanted their films colored and the black and white versions buried i'm sure he would agree,lol.
How different though are the star wars special editions and lucas, than a director who ran out of time and money, or the studio took their film away and then the director later finishes the film as they always had intended?
Sometimes even Novelists put out an "authors preferred edition".
