You do own the equipment - but you lease the software as per EULA - so technically, Apple COULD make the OS unoperable for jailbroken phones. They haven't damaged the equipment. The problem for users is - there's no OS you could put onto an iPhone (right?) So it would render the physical device all but useless. Again - technically - it's within their right to make the OS not available if it's been tampered with.
That being said - I don't think they'd ever do that. Bad PR and to some degree it's a great cat and mouse game. My guess is that an OS can and never will be 100 percent secure which means that someone will always find a hole and Apple will always repair/have another. The JB community and Apple both benefit by being able to test their security and make it an even better puzzle.
