I think it's one of those situations that is only going to be clear in some measure of hindsight. After all, any short-term benefit might be offset by the backlash when the media either evolves, or people (as they are now) gain access to foreign media sources. It seems to me that you'd utterly erode any sense of authority or trust you could build with your populace.
Shortsighted in other words, but what you'd expect from a gerontocracy.
