I'm not sure if you've been keeping up with US news, but this isn't true, at least until it's decided in court. GM, John Deere, and Ford all have the opposite opinion[1][2][3]
Not to mention I think it's currently illegal to Jailbreak an iPhone or root an Android, despite them being yours.
I really do wish the US was as cut/dry as you make it seem, and I wish they cared about consumers more, but in reality, Companies get far more rights then we, as consumers, do.
