The Making Halo 4: Infinity Multiplayer video that was released here on Waypoint was also put up on Youtube. However it has been removed due to a copyright claim by Microsoft.
I’m guessing this is due to the aggressive anti-piracy/leaks campaign going on at the moment. This is a case of friendly fire, but it would be nice to have it back up on youtube as its easier to link friends to in the future.
I’m thinking it has something to *do with Microsoft’s legal claims. (You can’t make money on Halo content on youtube) YouTube didn’t realize HaloWaypoint IS Microsoft.
