I think have heard enough conspiracy theories in one day to make me laugh. The best one's so far involve how Survivor is rigged in order to help minorities and bring them prominence. They note that the four winners have been:

Survivor 1 Pulau Tiga -- Richard Hatch, gay white male
Survivor 2 Australia -- Tina Wesson, white female
Survivor 3 Africa -- Ethan Zohn, Jewish vegetarian
Survivor 4 Marquesas -- Vecepia Towery, black female.

I'm suprised they aren't picking the winner of the fourth edition to have one leg, one eye, one arm, and speak with a lisp. Some people are just looking for any reason to complain when the one they like falters...
