Apple advertises the macs with macOS. So I suppose if you buy it expecting something else, that's on you, and the product still "works as advertised". They don't go out of their way to prevent you from running <not macOS>. I'll also note that few companies advertise their PCs as "general purpose computers", if by that you mean "guaranteed to run Linux flawlessly". Even System76 / Dell developer / whatever, which ship with Linux out of the box, don't guarantee the pc will run, say, FreeBSD perfectly. Don't get me wrong, as the GGP post puts it, I'd also like to be able to run Linux on a MacBook Pro. But since I don't want to have a wonky experience, since I understand it'll not work perfectly, I chose to put up with the wonky hardware of my HP, which works well enough.
