Any VIP program works on the (perceived) social standing that comes from (perceived) exclusivity. YouTube doesn’t want to alienate the traditional celebrities with ties to big media companies; part of that means stocking the VIP pool with only people that those celebrities consider to be their peers.
It's not that. YouTube is very worried about the copyright position of video game streams (ie. The stream clearly shows the copyrighted artwork of the games, unlicensed).
If they don't review the video, they can use the safe harbor provisions. If they look at the content and decide to promote or reward those creators, Google themselves could become liable for that IP infringement on aassive scale that so far is mostly going unprosecuted.
