Plus, what actually selling out means? This is a very broad question...It's like asking what virtue is(I am studying Plato right now, so I'm in that kind of thing now :D)
Selling out doesn't necessarily mean getting soft and diluting material for the mass market.
In my book it means taking the $/£ from the big corporates in sponsorship and promoting their big brands. Also it means being willing to share a stage with C-list celebrity bimbos.
