I know he said he didn't like Star Trek
in the interviews, but that was never my impression. I think he was sensitive to the way the work would be taken, and particularly to its potential to stimulate young minds to think about the implications of some of the things raised in his work or in the shows, if what he did was dismissed as the prattling of some fan of a TV show.
After all, he obtained hundreds of film clips from the show. Having done the same, I can say that is the way we used to do what we later did with video tape, and now do with screencaps, etc.
