The second point was addressed, though, by your own admission. It was punished (and if it happens again, I can only imagine the hammer will strike even harder).

If you don't like the MacBook, you can buy a Mac mini and use it as a build server from other (non-Macintosh!) computers. There are tools for other platforms, and Apple isn't obligated to maintain their platform for "non-standard" use. It's not antitrust, and it's not a technicality. They're not obligated to open their platform, because they're not restricting something that was previously open.

I don't like it either. That doesn't mean it's illegal.
