I get where you're coming from, but I think you need to understand that the vast majority of people (conservatively maybe >95%) are perfectly fine with using Amazon. If you just start metaphorically punching all of them you won't convince them of anything. I don't think you can really make something socially poisonous that way without a significant group of people, in socially powerful positions, already agreeing with you.
I think you're overestimating how many people think like you on both of these topics (iOS/Android and Amazon).
