You paid for the phone with the OS as a contributing factor (alongside the hardware) to the purchase no doubt, so the OS in itself must be compelling to you for some reason.
You didn't fund the development of the OS, contribute to it (presumably), you didn't market it or position it alongside your brand.
I'd agree with you if you said you have a right to run anything on the hardware under a different OS, but you have no god given right to run whatever you want on the OS.
Mounting pressure? As in, apply constant pressure to a thin piece of glass that is already prone to being dropped and broken? Am I misunderstanding or is this a terrible idea?
