You're getting downvotes, but I agree that Isaacman isn't likely to favor SpaceX. The space community in general is very supportive of him, and he's shown a great interest in spaceflight regardless of who's launching the rockets.

Also keep in mind that his previous missions realistically were only possible via SpaceX whether he liked them or not. Starliner was not (and is still not) ready, Orion isn't ready and is for NASA only anyway, and Russia/China aren't going to work well for geopolitical reasons. SpaceX is the only company left who has the capability to lob you into orbit.
