Theatrics. The DoD can overwrite musk if they want, they have full control over starlink via spaceforce. In fact the DoD funded the whole thing, musk was just used as a front so people dont get pissed the USA installed the biggest satelite contelation in orbit that has huge military applications.

Its a sure bet starlink is still servicing ukrainian drone ships. The DoD just told musk to spread some disinformation so russia cant claim in public that ukraine is using american satelites.
