The equipment used to communicate with the satellites is usually heavily regulated. For example in India you can't bring in items that communicate via a Satellite without a permit. In Kenya before they changed the law, VSAT terminals were heavily regulated. They had equipment that could detect if you had an unauthorized installation and you could get under heavy fines. Bottom line you can't regulate whether you can or can't get the signal, but you can regulate the domestic equipment required to communicate.
