So in your opinion if I install a sandboxing application on a Debian box and give it to, say, my little brother to use for homework, it's no longer a Unix-like because my brother can't open a terminal emulator and run ls? Do you realize how ridiculous that sounds? Do you also think Android is not a Unix-like because it's sandboxed? Besides all that, since I have to spell it out: those utilities _are_ present seeing as they're present in its base system, just not publicly exposed via Apple's official iOS SDK, and are trivially executable via `system` or `NSTask` (if you drop in the header file) on e.g. a jailbroken device. I mean, you do realize that iOS looks pretty much exactly like macOS under all the sanboxing?
