I'm not sure, but even with jailbreaking, iOS isn't certified UNIX. It doesn't have a command line shell built-in that you can access easily like macOS.

So I really meant "locked down" in the sense that you're not getting easy access to command line interface that can access system files without jailbreaking/rooting first.

I do think jailbreaking and rooting is easier than it used to be, but I don't mess with iOS devices much.

Most web developers I've worked with do not know whay a computer is, unfortunately.

I feel like I'm getting more and more on a limb using Linux as a dev. I'm working on a Linux only product and yet I'm the only one not on OS X and all the rest of them have to jump through hoops to get things to work, and can't run our system locally like I can. My last job was the same except 2 of us used Linux.

I can't even work out what they're getting out of it apart from the hardware. But when I tell them that developing from Linux is easy and comfortable they don't believe me.

professionals are more likely to prefer a locked down easy environment because of it's lack of variation the same way one would prefer a bare cli debian over a full featured distribution of even windows with all it's features and trinkets that can eat time away from the main task, mac os is bare and easy like a desk with nothing but a pen and clipboard, pretty bad if you want to fix a ventilator but perfect if you just want to write
