Fundamentally, it depends on the license. When this came up under Bush 43, the appeal was "the military is not allowed to use this!" and RMS and many others pointed out terms like this. This one is from the GPL v3 specifically:

> All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program.

Other licenses have similar clauses and a short list of requirements which must be met. Since the relevant groups, agencies, etc were (and presumably are) meeting the requirements, there's no grounds to revoke the license.

iirc, the Open Source Initiative stated that any claims/requirements limiting who could use the software or where they could use it would not meet the definition of "open source."
