There is no need to pretend. People with power want more power. As a thought exercise consider how you would arrange the world were you in a position to do so and try to determine placement of structures that could undermine your benevolent rule. Freedom of speech is such a structure. It is not really a paranoia if there are people out there working on just that. Now, just because there are also fellow travelers who truly believe 'for the children' cry, that is quite another and separate conversation.
