I'd say Pitbull even though I like him. Doing all those endorsements and commercials and such. Dude knows it's not gonna last forever so he's trying to get that money while he can. Can't say I blame him. Rappers don't normally have a long shelf life.
If the whole shit show of an article was true, then I'd have to say Steve Aoki.
Why? He's awesome and he is his own man. He owns a record label, he attended the University of California, Santa Barbara and graduated with 2 BAs; one in Feminist Studies and the other in Sociology...He produces who he wants and is a good person.
I have to add to my sell out list and say Avicii. I mean, he's gone all country and folk. How the hell does that belong in electronic music? He also uses Fl studio and Nexus presets.. WTF? This guy is the biggest hipster ever!
