Sounds like providing encrypted communications?

I think we can all see the potential problems with this, even if a specific group is awful.

“The specific claim: a far-left media group that describes itself as a “tool” for militants to share information “to be acted upon” used A/I’s services to publish communiqués and calls to action for U.S.-designated terrorist groups, including FAI/FRI, the IRGC, Hamas, Hizballah, ELN, NPA, PFLP, and PIJ. That same media group was cited in a federal complaint against a domestic terrorist sentenced to 19 years for attacking a federal building and a police car with IEDs.”
