I don't see the point to such a campaign, just seems childish and spiteful.
I won't be rushing out to buy a Subo or XFactor CD any time soon but at least the people who are buying them are doing so because they actually want them. So if they get to number one in a pop chart it's because they are popular, isn't that the whole point? The chart reflects what is popular, not what is good or what we personally might like.
Say this campaign succeeds. This song gets to number one. Has it done so on its own merit, because the people who bought it like it? No, they've just bought it trying to deliberately manipulate the chart because they personally don't approve of the music that is popular just now. Maybe not even that, they might just be jumping on a juvenile bandwagon and buying it for a laugh.
And this is morally superior to the XFactor how exactly?
