I too would like a more open OS for mobiles, but you have to realize that the majority of users doesn't care about this. They are unconcerned about most privacy issues, don't need to ever tinker at a low level with their devices, and they are the ones ultimately deciding on what the future will be. What matters is the UI, and that the various features "just work".
You are in a minority, however vocal, that has little to no say in what the future of mobile OSes should be. My take on it is that whatever will replace android and ios will be even worse on these issues.
