This comment feels like it's from the early 90's when people were being critical of bands for selling out.
AKA the good old times when it wasn't as culturally accepted to be openly evil if it made money.
Is there something wrong with being critical of bands for selling out, though?
That's a very different situation. An individual "anchoring their identity" to a brand isn't doing so to earn money, which is why bands "sell out". It's just a choice they make about who they are, and I have to agree with GP that that seems tragically uncool.
Except this is being critical of the popularity and fans, not the band.
Reminds me of Tool's reaction to that trend, "Hooker with a Penis"
