I don't think this will hurt them much - Apple is a consumer-oriented company, not government, business or education.

Students will continue to buy Macs and eventually the weight of all those purchases will bleed over into other areas, whether there are guidelines or not.

Governments will get a small propaganda boost for a bit, but eventually people will start to question whey they're so behind the times.

Business doesn't want to pay a premium for it's computer equipment, so no big loss there.
