Did you just suggest somebody leave their job because their employer wont let them install a software package on their mac-book?

Yes.

You have a job for me? In the North East or West Virginia?

There's loads of jobs on the east coast! And plenty of remote work even if you can't move. Start looking, who knows what you'll find.

Sometimes it's not about autonomy, but simply the availability of tools. Lots of software for various industries is OS-specific, so you may not have a choice but to use a certain OS for work (usually Windows, but macOS in the case of iOS development).

I agree with the sentiment but I think it very much depends on the role. I wouldn't expect iOS development to happen on another platform for instance. There are probably many niches with similar constraints.

Yes, of course, if certain tools are required to do the job then it's another matter.
