Jay-Z is a media star and therefore, he's going to say whatever is necessary to keep his fans around, until he doesn't want to be a media star anymore. However, he's also going to do what he needs to make money and if it's at odds with what he says, well, most of his fans won't even notice.

It's not that they're stupid, nor is he. He wants to make money and stay in the spotlight, his fans want music and fun, not a lot of deep political thought for which they don't even have the background.
