You're an idiot. The facebook campaign has nothing to do with Sony, it was started by Jon Morter, a 35 year old part time rock DJ, as a joke. He tried to rickroll the Xmas #1 last year but didn't get anywhere so this year he picked Killing in the Name and, in the way that things on the internet sometimes do, it totally exploded out of all proportion. The ONLY point of the campaign was to try and break the stranglehold that the X-factor have had on the UK Xmas chart for the previous 4 years and see if they could make the race for the Xmas #1 spot exciting again (something that, pre-X-Factor, has been a British tradition for years). The campaign succeeded and the icing on the cake was that Killing... actually got to #1.
And RATM only became involved a few days ago after some of their friends from the UK told them about it.
It amazes me that people are still peddling this recycled bullshit day after day.
Oh, and Cowell offered Jon and Tracy (his wife and co-founder of the group) jobs after they were so monumentally successful. And they turned him down.
