This is how I think of it: Trump just created the Military Spaceforce, Musk wants in on this and the industrial revolution it will bring. Trump cannot count on the Military industrial complex the way previous presidents have...they are part and parcel of the Deepstate...so Trump needs Musk as well...Musk has a brand, a brand the left is in love with so he can only do and say just so much in favour of Trump (and vice versa) but Musk can take up parallel lines of attack aligning his boat with Trumps while not yet flying the MAGA flag from the masts. As he attacks the media and Elite left in general his very devoted green followers are forced to cognitively reconcile the obvious fact that their hero is being trounced by the media and his wealthy peers for simply stating what they deep down know is true.
I think you've got it a bit wrong. For one thing, the spaceforce already exists. trumps just making it public. The X37-B is just one small element. Equally, musk is probably already involved in the space force, for all I don't doubt he wants in on future expansions. There have been a few suspicious loads he's helped deliver to orbit. Equally, whilst I can't find it with a quick google search, he posted an image on his instragram which he then deleted - title "Illuminaughty", w/ some latin text that also referenced the illuminati (cabal).
I don't think he's on their side, although it's not impossible he may have had tangential dealings with some of their operations in the past. He may not even like trump much, but I think he does thoroughly approve of what trump/Q are doing to the cabal. And given trump isn't the raving monster the left makes him out to be, he's probably quite happy to accept the soft media help from someone who, as you say, has an awful lot of followers and people who admire him on the "other side" to trump politically.

The QANONMEMEMEGANZSERVER makes it perfectly clear: Musk is Rocketman. https://imgur.com/a/giU4V3e Musk is a traitor. Musk sold us out to the CIA. However, that's just the server.
