If you buy apple ios hardware you are forced to use apple software. You cannot install lets say Debian. Not because it could not be reversed engineered enough to be built for it, but because apple has the walled garden's keys. Compare that to macbooks and x86 pc-s in which you could load anything you like. So apple are forcing you to use their software to be able to utilize their iDevices at all.
