According to most people's common sense, maybe, but certainly not according to US copyright law. Copyright law is very clear about under what what terms authors may license their work, and licensing it for indefinite time is not a requirement.

Edit: I'm just stating facts, not saying it's right. Personally, I see both sides. But if one argues that copyright law should be changed, I don't see why Amazon, a public corporation, should take away rights from publishers which have granted to them by the laws passed in a government supposedly representing the will of the people.
