Lots of people listen to him because he's a huge T.V. figure, not because of his facts anyway. He probably doesn't even know what autism is. From what I heard him say about autism from other aspies here on WrongPlanet sounds like he just watched Rain Man and read a couple of articles about autism, made a script, and made it into a show.
