For most Mac users, the only OS option is OS X. (Yes, you CAN run Linux on a Mac... but the experience isn't great. As far as I know, Linux still doesn't have support for suspend/hibernate when you close your MacBook Pro's cover. And although the Macs have the nicest touchpads, it seems weird to pay a 50% "Apple tax" if you're not even using Apple's OS. You lose half the benefits that Mac people buy into. So if you're a Linux person, then you might as well be using a PC.) Since most Apple customer's are using Apple's OS, when they don't like a change, their options are: (1) to switch to PC's, or (2) to hold off on upgrades, but eventually get on board with the changes begrudgingly. I've been seeing more #1's lately, but most fall into the #2 category. In the Linux world, however, there are hundreds of distro alternatives. And half of them are Ubuntu-based, anyway. Don't like the UI/UX choices that stock Ubuntu is shoving down your throat? In an hour you can switch to Xubuntu, Kubuntu, Lubuntu, or even Mint... and still retain compatibility with the same APT sources. Don't like systemd, or something else deeper under the covers? Then it's a little more effort to switch to a completely different distro family, but not MUCH effort. Open-source Linux distros just don't have the lock-in leverage to muscle their users around the way that propriety OS's do. By design.
