It'll be interesting to see how this plays out. Technically, the agreement doesn't require you to be nice. It just means that, obviously, Microsoft aren't going to pay you $3 CPM if you make a video that starts going "LOL 720p, beta tested in the future, PS4 for the wiiiiiiiiiiiiiiiin!" So it really needs to be tested to see if this violates any FTC rules. In theory, you should just be able to get your payout by playing an Xbox One game, mentioning that it's on Xbox One, and then basically talking about any old subject over the top. I've seen a lot of people do it. One guy basically played Super Mario 3D World while talking about why he took his Xbox One back.
