First of all, how do you know for a fact that the government doesn't publish everyone who speaks out, or is not moving in that direction? Speech certainly has become far more restricted in the last few years.

But even if what you say is true, it means that that speaking out has no impact on governmental policy, since if you start to have influence on the public you get shut up. And if that is the case, why should anyone ever bother to speak out.

Why don't you just admit it, you like living in a dictatorship.
