I can't imagine SpaceX helping Amazon to create a competing satellite constellation while they are setting up starlink
Worked for Tesla as well as SpaceX. Same goal for Boring / Hyperloop.
Seems like ubiquitous satellite internet would also be a good thing, and SpaceX would make money on the launch to fund Starship. Win-win? Silly logic from an armchair quarterback, but I don;'t think it's as weird as you think.
