Because morality does not revolve around the question "Will a megacorp lose some revenue?" There are many things companies and individuals could do that would make them money which they are nonetheless constrained from doing because those things are wrong. Also, the idea that users understand these issues and are passing judgment on them when they buy an iPhone doesn't seem realistic for the majority of iPhone owners. If you walked around polling iPhone users about this issue anywhere besides Silicon Valley, the most common answer would probably be "What?" And that's ignoring the fact that someone might object to this but still buy an iPhone for unrelated reasons. So even if their dollars could act as moral validation, I don't think it's reasonable to say they do in practice.
