Doing what you want with your own device? Us Android people have been doing that for a while. I've been running Cyanogen mod on my 2 year old G1, adding features TMobile refuses to add. I have an option that I can check that allows installation of packages outside of the market.
So it doesn't violate copyright, but it doesn't stop Apple from breaking rooted devices during updates. That type of legislation would, in my opinion, be overstepping the governments bounds.
