I work for a company that develops consumer electronics and we're working on a smart device that runs on an Android operating system. We recommend that our customers download the Amazon Appstore to get apps for the device because its screen size isn't compatible with Google's services. Can we legally pre-install the Amazon Appstore on our products before we ship them to customers? Does the legality change based on whether or not we advertise the fact that it ships with the Amazon Appstore?
Additionally, is there an obvious person or entity to contact about this? I've done a fair amount of research and cannot for the life of me find who I would even ask. We'd prefer to get explicit permission from Amazon itself but I've tried several different points of contact and never gotten so much as a reply.
