I agree that lack of a domestically controlled satellite communication service is a national security concern. If SA had a domestically controlled service and required citizens to use that instead of Starlink that could be a real national security measure. But a reseller of telecom services is not a telecom industry any more than a car dealership is an automotive industry. The actual owner of the satellite constellation can cut off access at will regardless of the domestic reseller's objections.

Furthermore this arrangement does not contribute to the economy of SA. It just makes Starlink services more expensive for SA consumers. The reseller is not really doing anything to develop an industry, but rather taking a skim. If the government actually wanted to develop the economy they would just let Starlink in for any real entrepreneur to use the internet access in remote areas to potentially expand business services into areas that previously lacked communication.
