Amazon tech support staff told me VERBALLY that providing firmware images for REPAIR purposes was "probably fine". I did not yet receive WRITTEN permission from their legal staff as I had requested. I suspect that their tolerance has much to do with whether our actions harm or help them. Their legal staff is aware of us and would send a takedown notice if they decided that our actions cause them more harm than good. We are helping them by providing free third-party support to their customers here.
EDIT: Even with verbal permission from amazon support staff, it is better to request firmware images using PMs. We do not want to openly publish direct links to firmware images here (or requests for them). We do not want to exceed the tolerance threshold of the amazon legal staff.
