Didnt slayer sell out with this album?

Diablos in musica is nu metal,they sold out just like metallica sold out with the black album and load,just like anthrax sold out with that rap song they did with public ememy and just like megadeth sold out with cryptic writings and risk.So why do they get a p? The only major metal band that never sold out in my opinion is the great pantera rip 1990-2000(i dont consider anything before phil anselmo pantera it was tacky 80s hair metal crap).Btw,why cant kerry king play good guitar after south of heaven?
