I actually debated a Cassini HB on the apollohoax boards, he never claimed a reason as to why, rather he was claiming that either NASA was lieing or idiots. The quick summary was that he read a press release stating the probes speed a short way to Saturn and how it was slowing down to a new speed, he took this to mean average speed and wondered why the probe was taking so long. He then argued that NASA should've used the Earth's movement to launch the probe faster, that Gravity from the Sun wouldn't slow it down, and that it should've gone to Saturn at full speed all the way. needless to say I didn't get very far -_-;. Anyways, as to why, I think he just wanted to feel that he had outsmarted NASA ("Look, they could've done this much faster if only they had ignored the laws of physics.").
