I think the major difference is that he didn't push his views about alternative medicine on others, at least as far as I'm aware.

We would have felt differently about him if he had published a book titled "iCancer: How I Beat The Disease Using Alternative Medicine".

Most of the other people weeded out of the gene pool by following quack medicine advice aren't pushing their views on others either.

(FWIW if Jobs had devoted an inordinate amount of time to encouraging his audience to follow quack cancer cures it would be a stain on his reputation but wouldn't diminish the value of his separate contributions to UX or consumer electronics)
