This is an interesting strategy. The "build a service for internal use, then make it a service" strategy worked for them with AWS and web stores, but it failed for Amazon Fresh (but they are trying to turn it around with Whole Foods), and now they're trying again with shipping logistics. Personally I've found them so-so, and certainly not great. I frequently get calls from drivers that are lost that can't find my new-ish street and need some help. It's certainly fine that the first one gets lost, but when the second one gets lost it's apparent that the organization isn't building up any knowledge about hard-to-find customers. This is a moat they could build, but they're not interested.
