Because there's no competition in Malaysia, we have to pay whatever Astro demands and accept its over-priced packages offering us channels we don't want nor need, and we have to accept frequent service breakdowns in the rainy season. Astro then takes that money to offer cheap services to Indonesians. If Astro had not burnt that amount away in Indonesia, it could afford to give you a 50% discount on your subscription fee for one year!
But it doesn't look like it's going to happen since it has a cosy, secure monopoly granted by the BN government. If our companies are big enough to go overseas, they are big enough to face competition here in the local market. Local consumers will then benefit from lower prices and better services.
