As far as the overarching point....none of those listed in the OP are strictly hip-hop. So regardless of who worked there their primary interest probably ain't hip-hop. Even if their staff was 50% black that's not a guarantee the publication itself would treat the genre with more respect, or that the black staff would exclusively deal with hip-hop, or that the black people they hire even have an interest in it.
It would be like if McDonalds started making pizzas. They ain't hiring a pizza guy. They're gonna have the fry cook make them.
So they're probably grabbing an alt rock guy and asking him to review a rap album.
Not saying it's right but it is what it is. I don't read anything music related from any of those places so I'm pretty
about it.
