How is Apple able to sell OS X for a profit when it's based off Linux which is open source/free?
Isn't that illegal?
Apple doesn't sell OS X, it's free on any mac. OS X is based of of UNIX, linux is also based of of UNIX, the systems have nothing in common with eachother.
It's not illegal, you're just ignorant.

But isn't this just using a loophole in Unix's license? Instead of commercializing OS X, they made it free, but put it on a product that you have to buy to actually be able to use it? Shouldn't they actually provide an official link/way to install OS X on other devices that are not Macs?
I don't think you understand how licenses work. Apple is a gigantic company, if they were somehow in violation of some license then you know some freetards would be on them. As far as I know, they fulfill their obligations by contributing to Darwin.
UNIX -> BSD made using UNIX code -> lawsuits -> some hipster college makes unix-like clone of UNIX kernel to be used in BSD -> apple nearly bankrupt due to how utter shit MacOS is -> can't wait any longer and takes unfinished balf baked mach2.5 kernel, shoehorns in missing parts with BSD code, and calls it "innovation" -> tries to actually market it as UNIX
