Switch From Microsoft to Apple?

I believe the reference is to Microsoft's early 90's practice of requiring vendors to buy a windows license for every computer they sold, regardless of what operating system the computer shipped with.

From the Justice Department's complaint

Virtually all major PC manufacturers find it necessary to offer Microsoft operating systems on most of their PCs. Microsoft's monopoly power allows it to induce these manu- facturers to enter into anticompetitive, long-term licenses under which they must pay royalties to Microsoft not only when they sell PCs containing Microsoft's operating systems, but also when they sell PCs containing non-Microsoft operating systems.
