I haven't heard anyone claiming starlink is a threat to security, Chinese or otherwise. It was criticised for polluting space with lots of worthless satellites.
He clearly is part of the establishment, and even has security clearance thanks to SpaceX. However a lot of stuff he's said has put a target on his back. Wanting free speech on twitter being the primary one. Because of his business interests, he can't really be anti-China.
I think he will be taken down, but it'll be interesting to see how it happens.
