Even if anti-satellite missiles are too expensive to be used to shoot down thousands of targets, the ground stations could be bombed instead. Hacking the control plane and sending de-orbit commands could be even cheaper.
Starlink satellites use inter-satellite lasers and can send those signals arbitrary distances via multiple satellites. Taking out a ground station will just require routing changes and the constellation will continue to perform.
And you can't just wave around "hacking the control plane". Russia's been trying to interfere with Starlink for a while and they haven't had any long term success. And finally, even if the did somehow get access to the control systems at SpaceX, the satellites can't de-orbit quickly. It takes weeks to de-orbit, over which time they could be commanded to reverse course.
The new generation of Starlink satellites have laser connections between them (which is what the article is discussing). They can send data to the other side of the globe to a friendly country for the ground link. (That’s a less efficient use of the inter-satellite bandwidth, of course, but worth doing for war.)
