The U.S. Pentagon is preventing the Russian military from using Starlink internet terminals operated on the battlefield in Ukraine, John Plumb, Assistant Secretary of Defense for Space Policy at the U.S. Department of Defense, said in an interview with Bloomberg on May 9.

“At this time we have successfully countered Russian use, but I am certain Russia will continue to try and find ways to exploit Starlink and other commercial communications systems,” Plumb said. "It will continue to be a problem, I think we’ve wrapped our heads around it and found good solutions with both Starlink and Ukraine.”

SpaceX is working with the DoD on this and even the DoD thinks it's going to be an on going problem.
