Basically because it is partly owned by MS by being the publisher. MS gave them the money to make the game. In this instance Gears of War and it's sequel probably cost tens of millions to make. Without that money there would be no game. MS have always had good relationships with other devs but it has always revolved around money. It is just the way the world is. If someone has money and will pay you to do what you like doing then your always going to think nice of them. If you don't give them money or help them then your not going to get very far. I think Sony in it;s early couple of years was a fine example of this.
