> SpaceX is the one direct competitor. You never [fund] your competitor.
This would be astonishing to Apple (which buys phone components from Samsung), Google (which pays Mozilla and Apple to be the default search engine on their browsers), or indeed Amazon itself (which sells Apple and Google products that directly compete with their own, buys software from Microsoft, licenses Microsoft software for some of their cloud services, etc.)
On the other hand, you’d be surprised to see Apple launch an entirely new product and then select, as a primary supplier, a side business owned by Tim Cook with zero track record of delivering the necessary service.
Jeff Bezos’ side business, Blue Origin, has been unsuccessfully trying to compete with SpaceX for years. This unsuccessful competition rose to the level of public feuding and lawsuits against NASA for selecting SpaceX over Blue Origin for their moon lander contract. Suddenly, Bezos’ main business, Amazon, launches Project Kuiper to directly compete with Starlink, and contracts with Blue Origin for launch services that Blue has zero track record of successfully delivering on, as well as ULA for launch services using Blue Origin rocket engines that Blue has zero track record of actually delivering. This is an obvious case of conflict-of-interest and self-dealing.
Amazon does not need to launch new products and services for the purposes of satisfying Jeff Bezos’ personal rivalries and grudges in the first place, let alone shifting Amazon’s cash flows into his struggling side business.
