Based on some old tweets, I think Musk believes Putin wants to use nuclear weapons. Then, the army put some pressure on him to keep supporting Ukraine, but he is still also working on his own. I’m sure he could block the Starlink terminals Russian army is using, if he wanted to try, for example.
I actually don’t know. I didn’t dig into it, I just read an article about Russians praising Starlink bought through third parties used at the front. It seemed similar enough to other captured communications previously shown as accurate. But it doesn’t definitively prove anything for sure. It could’ve easily been propaganda from any involved party.
