“Tyrannizing the Marketplace of Ideas” is better put as stifling and eliminating innovation in order to achieve absolute government control of everything including citizens personal lives.
That is the same exact thing that Xi Jinping, the Dictator of China, is doing to the Chinese people who hate him and the CCP.
How deep is the hate? Unlike the tyrants before him Xi is trying to bring in traditional Chinese beliefs like Confucius (Socialism with Chinese Characteristics) . Like Gorbachev before him , Xi might find out once you open the door to open thinking Communism crashes.
