Be happy they are only enforcing the rules rather than taking away the free service completely. Be happy you were given this gift in the first place. Imagine what it would be like if it was never given.
Also consider they are strictly following the rules w.r.t. HIMARs and not firing them into Russia.
The US is a large contributor to covering the costs as well. The terminal is the smaller part of the cost, connectivity is an ongoing cost. Even if they were paying, there is an agreement or ToS for all customers.
