Depends on if the courts look at this as a hardware issue or "digital" software one. I have a feeling they would look at like renting physical hardware in which the first sale doctrine would absoltely apply.
of course like with anything in the legal system it will take a company like Amazon that has their own team of $1,000/hr lawyers to face up against Apple's team of $1,000/hr lawyers in order to get a precedent setting case
