Not entirely. He's showing he can punish his in-country critics and get away with it; do that often enough and they'll keep quiet no matter what sources of information they have.
Hugo's statement actually means he has total control over all media, since all he has to do is claim they are advocating a coup.
He's been doing that since he was elected. There's a long list of businesses he's grabbed, closed, nationalized, stocked with employees that are loyal to him, etc. I don't see the point of one TV station when FL is filled with the remnants of former business owners that have fled before they could not. Anyone who lives there already knows what he is capable of. He even sends the police to harass our Ambassador if he dares to leave the Embassy grounds.
