This is exactly why I think phones are such a huge step backwards as far as personal computing goes. Even though in theory you own it, you basically don't.
You can't install/uninstall software, configure the device, etc., etc. as you see fit. Many phones are cluttered with software/services you may or may not want, the carriers feel free to do things such as the MDM mentioned above, and many of the apps can be filled with security/privacy issues.
(I'm amazed at the HUGE laundry list of areas on my phone that many simple apps want access to, and that I know damn well they don't need/don't have anything to do w/ the app's purpose. )
At least my PC has the illusion I'm in control (and using Linux I do feel this is more than an illusion), and that I can configure it as I see fit.
I frankly don't see the appeal of smart phones at all: You are locked in, everything you do is tracked/reported on/etc., and you have to pay for the privilege.
