Honestly I've never got this, 'Theory'
There seems to be this general view among indie fans that if band/artist makes it big they've sold out. This baffles me how are they now 'crap' because they have gained mainstream success? By that standard The Beatles would have been wiped and flogged by their Cavern Club following. It's becoming a hindrance to bands and it's part of the reason that guitar bands are being restricted in the charts as their hardcore following is small and changing to a pop sound (Which doesn't always work) risks them losing it. Why is this? Why are bands forced to remain unsuccessful or risk losing their hardcore following?
Examples of 'Selling Out'
Green Day: 'Sold Out' with American Idiot when really it was there last listenable album.
Paramore: I've always hated them but apparently they again 'sold out', the few songs that are bearable are from that period of selling out.
The Strokes: They started experimenting? HERICS.
Bloc Party: Again, Experimenting=Selling Out.
Linkin Park: A move away from hardcore? SELLING OUT! (Still hate them).
I could go on but I'll end it here. Discuss Flood
TLDR: Apparently if you don't continue being Indie you're the worst band ever.

Yeah, I don't get that concept either. A band makes it big, that's good, they are making more money, be happier for that band. A band changes their music style, that's fine, if you no longer like it then simply don't listen to it, that's something up to the artist's personal decision, nothing you can do about it.
