You're not getting it. He will make money from this. Like Hal_Jordan said, he trolled someone and won. Why wouldn't he do it again? If he knows it's so easy to make Kanye snap, why not push his buttons more and sue him again and again and again?
I can't believe people are actually arguing in defence of Kanye. When you let the trolls win, it's your own fault. If people snapped every time someone shouted a slur at them (racial or otherwise), our society would be in anarchy.
The kid is a punk, no one is denying that, but Kanye is an idiot for going after him. He let the world know exactly what will make him snap, and now he's set himself up for more of this. Had he let it go, the kid's slurs wouldn't have been given any power. If Kanye can't handle the trolls, then he's in the wrong business.
