I like that idea quite a bit!  He would be acting less like a vice and more like a sieve, allowing only certain information to reach the ears of the population.  The public would get anxious if they received no news at all, so his job would be to keep them distracted, alleviate their fears, and entertain them to ensure that all unpleasant "incidents" can slip by unnoticed.  As he does enjoy getting into people's heads, figuring out how to "spin" stories to work in the favor of the Black Dragons seems quite up his alley.
