Wait a minute. ITU is composed of the national regulators and interested companies. ITU cannot regulate, they can simply recommend that each regulator goes home (in US case, FCC), and proposes some regulatory change, which has to pass normal due process. So this it not a matter of UN or ITU applying regulations.

With this said, I think it's best for ITU (and regulators) to keep it handsoff with the internet. ITU has a history of complicated and old-fashioned standardization that would do more harm than good.
