My opinion is that he got seriously blackmailed. Musk meets Netayahu 27 Nov, and on 12 December its announced that SpaceX loses appeal for 1B in funding from the FCC regarding Starlink. There's probably lots of variables for losing the appeal, but considering how far the isreali lobby goes I really wont be surprised that they had influence, considering he was making Starlink available in Gaza for free.

And this is just the surface we can see, I wonder how far the rabbit hole goes, hes probably in the top 5 most famous people in the world, whatever he says online will reverberate far, hence the israeli top priority being to change his mind carrot or stick. In addition, he admitted to having a mild form of Aspergers, so I guess social pressure and persuasion definitely impacts him differently than neurotypical folks.
