While there are direct references to the CR in the first few chapters, the real cleverness is the indirect approach and the (traditional) use of SF to critique the present society. In the book, advanced higher-dimensional aliens have invaded earth .. with a pair of subatomic particles. Since these are under their full control, they are able to warp reality in higher-order physics experiments to prevent humans ever learning certain things.

The parallel with the CR and Maoism (or indeed post-Bernays propaganda states) in general is obvious - the ability to finely control what information someone receives, especially at critical moments, is the ability to control what they think and know.
