Do you want a single monopoly controlling this? That type of situation has historically been bad for innovation.
As an analogy, how would things be if every internet web app created had to operate at the mercy of another company? Startup A has a great idea and wants to release an innovative new webapp. But they need to pay and have permission to do so, must operate in a tightly defined sandbox, and must share profits that they make. And the webapp could be kicked off the internet at anytime for breaking these rules.
Does that make you comfortable?
