Ah sorry missed the part about mobile. But in any case, this isn't true, there has been playground for quite a long time on iOS. The portions of BSD which XNU uses is quite small, and is quite a mismatch of things from all over like IOKit and mach, mostly taking inspiration from L3. The drivers are custom, graphics custom, custom touch input, etc. They actively pay developer salaries at LLVM, cups, many other open and important nix projects. This comment seems misinformed and griping, there are plenty of ways to program on iOS. There's the developer program, TestPilot, and more.
