Please do not quote my post out of context.
No context in the world could make that statement I quoted true, but anyone on this forum can go back and read your full comment if they think it does. This was just a cop-out reply to avoid dealing with my example demonstrating the statement was incorrect.
I am understanding you perfectly but you are not understanding me. The concept of being able to do what ever you want with the device that you own is the ability to remove the OS from the hardware. This is not a software issue, it's a hardware issue being the case that the hardware should be able to be seperated from the OS (software) . Why someone would want to is not the point here, the point here is that they should be able to do it but they can not which ultimately means their ability to fully own the device is limited. Basically it's limited to how ever Apple want it to be limited, ergo you do not fully own your own device.
If you had the technical know-how, you could physically remove and replace components on the iPhone to accomplish your goal to remove the OS and replace with another. But then one could argue it's no longer an iPhone.
But that's not even what the person I was replying to was wanting to do. The people I respond to with the facts about hardware vs OS are wanting to use iOS but be able to side-load apps. They argue that they should be able to because they "own their device"--seemingly forgetting that iOS is software, not hardware ("the device").
