They already did in the past, Apple doesn't have that big customer size outside US and similar economies.

The Quadras and LC on my campus back in the day were a very special breed, as the IT department even had a couple of NeXT cubes.

The peasants would get thin terminals to DG/UX and later on Red-Hat, or Windows 3.x/95/NT, depending on the laboratory.

It's not like you often see Macs in education, even among students !

I personally manage a lab of Macs running LabView at a university, in a department that uses at least 75% Macs overall.
