Because people know that the public love a good dull winner, hence why they're placing money on him which has made him the favourite. I don't blame them, it could happen
That said, I do find him interesting and likeable, and if he had some kind of documentary about his life or something where he could talk about his view of the world I'd certainly watch it, he seems to be quite clued up on things and has some intriguing personality traits. Unfortunately Big Brother is the wrong platform for that kind of thing, and he really hasn't done anything in the context of
this show to warrant winning.
