VTFW states that it's not that they don't like the show...they do, in fact. Their main gripe is that they think the producers showcase and highlight the ones THEY want to win and, therefore, manipulate the outcome. I have observed this since IA2, myself, but I think that the producers are in the business and know better who will and will not sell records. That's their bottom line, after all.
However, that being said, I also think the producers have a finger on the pulse on the record-buying public when they make their decisions to subliminally tout some contestants more than others.
After all, any contestant who's really any good will get a record deal whether they win or lose.
