There is reasonable freedom of speech (many say Roherum still broadcasting on the Fairy News Network is proof of this) but there are official lines to take (which FNN inevitably does take. They do know which side their bread is buttered. Freedom for them has its limits).
So what freedoms does your fictional world have? If there are restrictions how severe are they? How are they policed? Are there resistance movements (especially if your world is more despotic than benevolent)? Were there restrictions initially or were they brought in due to certain events (and if so what were these?).
Freedom is not all that it appears at times. How does your world(s) reflect that?
