I'm reminded of a leaked document on Soviet official censorship regulations, from around 1970, and translated and reproduced in the book "Party, State, and Citizen in the Soviet Union: A Collection of Documents".
There is a long list of things that may not be printed without official approval.
Details of trips and speech locations of members of the Politburo, the Soviet Union's top leadership.
The censorship system itself.
"Activities of the organs of state security and intelligence organs including:
treason of the Motherland, spying, terrorist acts, diversons, anti-soviet agitation and propaganda, mass disorder, participation in anti-soviet organizations, illegal departure for abroad, information about facts of the above-mentioned crimes."
Amounts of various sorts of criminality.
Details of prisons like how many people imprisoned and under what conditions.
The number of homeless people.
The number of illiterate people.
Information entailing human victims of accidents, wrecks, serious accidents, and fires, without the permission of the responsible ministry and department.
Info about the consequences of catastrophic earthquakes, tidal waves, floods, and other natural calamities (the general amount of damage to buildings and structures. no. of human victims, damage expressed in money terms).
Info about the number of fires and their victims.
Revenues and budgets for the Soviet Union and its constituent republics (much like US states).
"Calculations of the purchasing power of the ruble and of the hard currency of foreign states."
Details of foreign investments and the income from them.
Income vs. spending for the population.
Information about the preparation for visits abroad by Soviet government delegations, and for visits to the USSR by foreign delegations.
Information about mutual governmental accusations (charges) between the USSR and foreign states, about judicial matters, investigations, arrests, etc.
Info about hostile actions in relation to representatives and citizens of the USSR from the population or responsible figures of foreign states.
"The correlation between the cost price of service for foreign tourists in the USSR and the selling price of tourist trips to the USSR."
Details of the export of military hardware and military assistance.
Details of low morale and poor conditions and poor discipline in the military, and poor relations with civilians.
How many drug addicts.
How many people have certain infectious diseases: cholera, Yersinia plague, typhus, and smallpox.
Details of occupational injuries and illnesses.
Info about the audibility of the radio stations of foreign states in the territory of the USSR.
Info about the duration of the conducting of all-union training assemblies of sportsmen; about the rates of pay of sportsmen; about the money prizes for sportsmen for good results in sport; about the financing, upkeep, and staff of (athletic) teams.
Me: the Soviet Union had the pretension that all its athletes were amateurs, and professional sports are part of the degradation of capitalism. I remember someone being outraged that Soviet-bloc Olympic athletes are professionals. I didn't see how that was a big issue, since the only way to compete in the Olympics is be a de facto professional. I think that the Olympic management ought to drop its pretension that Olympic athletes are all amateurs.
