iOS is a nightmare of user-unfriendly restriction.
Even Android, while fairly restricted, and not rooted by default. Is much more open and free in comparison to iOS. And at least, on some level, starts to approach Windows-levels of user customizability and freedom. At least for the mobile market. Once you root your Android device, you're fairly free to do what you want, outside of the confines of Google and so-forth. And makes a fairly decent "PC" or tinkerer's OS, while iOS isn't much good for doing anything outside of Apple's fiercely gated walls.
Android is far from perfect. Ubuntu is, and SteamOS will be much more freedom bearing than Android. But it is still a much, much better option than iOS.
