Starshield is communications provided by US military using Starlink satellites.

AFAIK, Starlink has been velocity gated in Ukraine all along. Starshield wasn't. Till now.

I guess Musk could order Starlink engineers to limit Starshield in various ways, but then he would be in breech of contract with DoD, probably a bad move. This seems to be a DoD decision.
