It's not clear from the announcement that they are giving up all first-party payments to Stripe. > Stripe will become a strategic payments partner for Amazon in the US, Europe, and Canada, processing a significant portion of Amazon’s total payments volume across its businesses, including Prime, Audible, Kindle, Amazon Pay, Buy With Prime, and more. That makes it sound like some things (and certainly a significant percentage of the total) will be processed by Stripe, but not all spend. For example it doesn't seem like normal purchases on amazon.com would actually be processed by Stripe at this time.
