What makes Apple valuable is precisely its full vertical integration. Nobody else does it at that scale except maybe Sony for consoles and Microsoft but both don't have the same usage coverage and thus integration.

It wouldn't be economically rational for Apple to bring down its own moat.

Folks are much better supporting Linux and BSD OEMs than buying Apple than then trying to run Linux on their devices.

They don't care about people buying MacBooks. They want you in their ecosystem buying i-everything.

I do wonder if the margin on Mac isn’t that high vs the price and the services (iCloud etc) make up for that.

Amazon do the same with the fire.
