Anyways, he's not totally wrong, but as always (like with the Ice Bucket Challenge) people underestimate the value of celebrities promoting a cause. I already know many of these celebs legitimately donate a lot of their own time and money to causes too, so it's not the end of the world if they jump on a charity single. Too cynical
I do, however, agree with what another poster said about the continued depiction of Africa by the media being troubling.
