My 0.02 cents. Why can't the government protect its citizens rights. America was built upon Freedom, and now we have this company creating an entire ecosystem of proprietary add ons? And if the Devteam decides to become an enterprise they can be sued under DMCA? Now the government just told everybody that if you want to create an enterprise that wants to develop, sell or give Iphone users the possibility of having their phones with another OS, applications, etc...you can. If there are customers that are willing to pay for it, use it, it is their choice. For the ones that wants to continue on the Apple ecosystem, they are also free to continue there as well.
The implications that I see, is that we will see more apps that although does not break the law, will impose a large toll on the Network side, like tethering and that probably is not being controlled by the DMCA.
Using an analogy, if you buy a Honda Civic, and decided to install a dual turbo on it, get new dials, and so on, you are entitled to. Honda will make its warranty to the parts of the car that you haven't touched right? That's what I think Apple should do, also, if you have installed a dual turbo on your car, it is understandable that you will be racing. Now if you race on the track is all good, if you race on the street, it has nothing to do with your relationship with Honda, you are breaking another contract, with the law that your government has stipulated.
It is all good, it will only allow other companies to tackle on the Iphone, it is up to you to buy from those companies or not.
