They will undoubtedly sell some aspect of Kuiper through AWS. They already have IP addresses and DNS in the AWS product list, and they have all kinds of data transport services.

I don’t know if the government implication is as big as you think, as the US government has been doing secure satellite communications for decades and has already given SpaceX the contract for Starshield. So undoubtedly Kuiper would love a piece of the action but there is already competition and Kuiper is a bit late to the game.
