If you find that BB cure...Well it just seemed you didn't understand why someone could vote because they were a fan rather than because of whatever non-popularity based criteria the production staff invents.
At least SYTYCD generally only has good dancers on it and sells its winner as America's Favorite Dancer.
I just think brainwashing implies the person asking for the votes has more control over the minions than they really do. Most of the minions are a bit too fickle to be suffering from real brainwashing and any avoidance of anyone with a different viewpoint is voluntary.
Now that you are a rabid fantarding minion doesn't imply intelligence, but it doesn't mean the source of the irrational devotion is deliberately forcing the minions to be in their rabid fantarding groupie group rather than someone else's rabid fantarding groupie group.
