Maybe because the band used to be great and became massive commercial sell-outs who make fairly boring music these days. Just a guess.
In what way are they commercial sell outs? They've been massive ever since Origin Of Symmetry
was released, so unless you've been listening to them since 1999 or something, they've more or less stayed the same levels of commerciality for about 10 and a bit years.
Also, who the fuck still calls bands sell outs?
