Surely campaigns such as this (and the RATM xmas no.1) are hypocritical. They're trying to stop an 'artificial' number one, but in the process are 'artificially' manufacturing an alternative number one.
Whatever happens, Simon Cowell wins. I agree with [MENTION=16867]Finally Falmer[/MENTION] - this would just be an alternatively engineered artificial number 1. What these campaigns actually do is create a sales war that would not have happened otherwise. This will almost certainly result in the X Factor winner's single selling more copies, even if it does only go to number 2 in the charts.
As an example, my (musically-taste-challenged) girlfriend bought Joe McEldery's single the other year, simple because she didn't want Rage Against the Machine getting to number one.
