I don't know about this argument though. If Amazon bans a book based on their ethics, people freak out about censorship and how one company has so much power and shouldn't be doing that. If their AUP stated what they deemed ethical, how many potential startups or corporations wouldn't be able to start? Take a "simple" example: A business that counsels families on abortion. Is that ethical? Who gets to decide that? I think this is one of those cases where we have to be very careful what we are asking for.
