I feel like a lot of this is also the case with Apple's ecosystem. People get used to having specific apps and get complacent. In that case though I feel like another driving factor is the financial investment when you have iOS and MacOS apps, an iPhone, an iPad, and so on that all mesh with each other.
I know so many web developers who use MacOS, and I think it must be because of the command line. It's like Linux is still too scary, even for professionals.
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.
This, and the general business ecosystem. Few companies even ship hardware with Linux support, especially at big business scale. I didn't even see an option from Dell any longer, Lenovo has one machine it looks like, so you'd be going for something like System76 which operates no where close to the same scale.
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
I feel like I've seen TestFlight used a fair amount lately.
I have no clue what the jailbreak community is like anymore. I've heard Cydia isn't really a thing with newer versions of iOS so I have no idea how lockdown iPhones are anymore.
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.
