I don't see the problem with this. All Microsoft is doing is paying and supporting the content creators supporting them. If other content creators who aren't fond of the Xbox Brand, decide to jump aboard and sell out on their personal beliefs for money, that's their fault and Microsoft's gain.
Just like any business contract, which this is, by the way, you aren't legally allowed to discuss the terms, conditions, or what you receive from it, so whatever.
The "you can't be negative about the Xbox One and it must be relevant" part also makes sense, why would the support you trashing their product? Besides, it's necessary. You already saw some posts on GAF discuss loopholes and ways to get money from Microsoft without doing anything. "Put it at the end of a totally unrelated video! Make a video discussing this bullshit and make money since it's about the Xbox One! Tall badly about the Xbox One and tag the video so you get paid!"
Can't blame Microsoft.
As a content creator and YouTuber myself, my channel is already practically a Xbox only channel (thanks Sony for making it so hard and BS to capture PS3 footage! And thanks even more for not allowing PS4 footage at all!), so I'm just getting paid for doing what I already do, I don't see the negative. Microsoft is just supporting those supporting them.
I know you're being sarcastic, and the hidden tag is hilarious, but seriously I sort of agree.
