The subject being satirized in this article is hip hop/rap "criticism" that's just thinly veiled racism/racist dog whistling. Not Ozzy Osbourne. They’re using a real news item about him in order to satirize racism because his reason for denying use of his song subverts the trope of the “old guy who hates rap for racist reasons.” Ozzy is not the butt of the joke here, but please, don't let that get in the way of your righteous indignation and pearl clutching on behalf of Ozzy.
