it is a subsidiary. Ie. Amazon pays A9 for the technology, but A9 is a separate legal entity. I worked developing for the Kindle, which is designed/engineering in Cupertino, by a company called Lab126, which is a subsidiary of Amazon. (basically Amazon pays Lab126 for technology transfer on the books, but really, internally amazon controls everything). The Parent company/legal entity of the CA subsidiaries is called A2Z. We were instructed not to travel around, we couldn't attract recruits by saying we were working for Amazon, etc. etc. But internally Amazon was controlling pretty much everything.
