Apple makes hardware that runs macOS. They do not make hardware to run Windows/*nix. They do not need/want to support those other OSes, else, they would make a product that would do that. They have theirs and they feel it is perfectly fine for the product they are offering "thank you very much". Since day one of Apple, the Steves argued open/closed system. Up to the Apple II, Woz won. With the Macintosh and ever since, Jobs won. It is now Apple's ethos. It is theirs to decide. You are free to not like it. Others don't like it, shrug their shoulders and choose to do it anyways. Some of them will even share what they've learned, and some of those will even do that well. If you choose to follow, thank them, and join the movement. Complaing that a company isn't doing exactly what you want just seems sad and pathetic to me.
