The thing was that with computers we had the BIOS, that defined an open (well, in the first days it was proprietary but became a de facto open specification) that allowed interoperability between hardware and software, to the point that it provided the most basic functions to be able to boot whatever operating system you liked.
We should have done the same on the mobile, there is no reason why this works on computer and not on smartphones, if not commercial reasons. Why on a macbook I can install Linux but on an iPhone I can't boot whatever operating system I want? It's not a matter of security, because it's the user that chooses to change the operating system.
