Yes, I&#x27;m well aware of these restrictions. However, I don&#x27;t think they impact whether or not you own the THING.<p>What GM, Ford, John Deere, Apple, etc. have said is that you can&#x27;t tinker with their firmware that is installed on the device. None of them would argue that they can come repossess your tractor&#x2F;car&#x2F;mobile phone.<p>As others have pointed out, it is not currently illegal to jailbreak a phone, though that may change in the near future.<p>To make an analogy and play devil&#x27;s advocate a little further, it would be hard to argue that I don&#x27;t own my home. There is a deed to that effect recorded with the county, more than I can say for anything else I own. Yet:<p>* The state can take it from me in short order if I don&#x27;t pay my taxes<p>* I have to get a permit from the city to make any substantial modifications to the property<p>* There is a neighborhood association that dictates property uses as well, which I have to comply with<p>* I couldn&#x27;t just knock the house down and build a car repair garage -- city zoning ordinances restrict how I use my property.<p>And yet, I don&#x27;t hear a big outcry that I don&#x27;t truly own my house.
