When you censor, the people you are censoring lose power, impact, communication, voice, influence.
These people are less powerful than those guiding the censoring. This means they run into more suffering, and learn about more problems. Some of them get deep, deep into the problems.
When censored, these people die, and the problems become unlearned of.
When not censored, these people make an irritating stink, and people learn of some of the problems. Problems nobody could ever imagine. Problems that have learned to never be noticed except by their victims.
