They used to though.

Years ago in communist Poland my father accidentally wound up in some kind of Chinese event where the organizers would give away Mao's Red Book.

At the exit there were two local secret service agents who in turn would politely, but firmly ask for the booklet to be surrendered to them, since this was a flavour of communism not enjoyed by the Big Brother, so illegal.

They used to when Mao was alive and the country was engulfed by misguided idealism. After Mao was gone they realized what a mistake that was, hence why China started reforming. The party’s official stance is that Mao was 70% right (pre-cultural revolution contributions to freeing the country from oppressors, giving common people power), 30% wrong (cultural revolution).

So whether they used to or not is not relevant.
