From a Slashdot interview with Neal Stephenson in 2004:
"I embraced OS X as soon as it was available and have never looked back. So a lot of 'In the beginning was the command line' is now obsolete. I keep meaning to update it, but if I'm honest with myself, I have to say this is unlikely."
Many people since 2004 have "embraced" the whole Apple ecosystem of tools, hardware and software.
They actually cannot look back now. It's literally almost impossible for Stephenson and many other of our contemporaries to look back and choose another way. To do so is literally more pain than is worth. To even contemplate an alternative means negating the investment in Apple. To turn your back on the investment of time, money, effort would mean the benefits of change would need to be greater (or the pain of staying would be worse). It's not going to happen: those who embrace Apple remain within Apple's bosom.
What? Did Sierra stop being Unix and nobody's mentioned it before now? Or is there something about owning a MacBook Pro that makes it impossible ever to buy a Thinkpad again? Something about owning an iPhone that makes Android unimaginable?
Perhaps you'd argue that there is. In order to do so, you'd need to explain why there is a distinction to be made here between Apple and literally every other software and hardware manufacturer on the planet. That such a distinction exists constitutes an implicit prior in what you've said above. I don't agree even that that is true, let alone that it's self-evident. You have the opportunity to convince me otherwise.
The key part of my comment was the "embracing the _whole_ ecosystem" (whole) In other words, if you are with Apple 100% it is actually much harder to buy a Thinkpad again, because it hurts your investment in the brand.
Yes the core is BSD derived unix, but OSX is also a massive layer of libs on top that is proprietary to OSX.
So unless the developer takes outmost care to not touch anything that makes OSX, well, OSX, its damn hard to transfer anything over to a _nix from OSX.
In other words, writing portable software is harder than writing non-portable software. Fair, but I don't see what it has to do with the matter at hand.
