If your local supermarket A-Mart sold A-Cars that refused to drive into other supermarkets parking lots then yeah. You could argue that you don't like other supermarkets practices and want to ensure you or your spouse or your parents don't accidentally drive there so you buy A-Cars for all of them. And it isn't a monopoly, these cars have only about 50% market share, if you want to go to another grocery store why not buy their cars? Anyway, the point is that coupling things unnecessarily is dumb. There is no need to enforce coupling of hardware and software like Apple does, the only reason is to ensure that Apples strong points also lets them sell their weak points.
