I've never said anything about "freedom"... Driver is used by applications as an interface between the OS and the hardware. It's not just that it's default. The OS was clearly designed with that in mind, whilst Android makes it pretty clear that rooting it is undesirable. If you root it and if you get access to the shell, then you can probably do everything I asked about. But you have to go through hoops and loops to achieve that state. Or, of course, you can use 3rd party solution, but that doesn't count as a capability of the OS.
