Re: Vendor support is one thing...
"Have you ever tried to play a Blu-Ray DVD in Linux or *BSD? What about streaming 4K Video from Amazon? How about playing "The Division" or "Mount and Blade 2: Bannerlord" or "Destiny 2"? All of these will required breaking the T&C's to work, if they work at all."
Sure, but none of them are things you need to do (or ought to be doing, if your employer is paying...unless you work for a game developer...) on a professional workstation.
I dunno, I used to care about that stuff a lot more, but a decent blu-ray player costs like a hundred bucks, and everyone streams movies these days anyway, don't they? Plus a PS4 plays blurays just fine. Plus it or just about any cellphone can stream video fine. I gave up worrying about whether I can play movies or games on my desktop/laptop computers, oh, I dunno, a decade ago or so. I have other things for doing that.
