What is the difference between a “code of ethics” and “strict censorship?”
what's a present-day example and a past example of a country who censors the press; thereby, limiting “the truth”—objective information—to the public?

Code of ethics are guidelines while censorship is a rule of law. There are some technical laws in the nation that may allow for this to happen if it is pushed.

Explanation:

Code of ethics are general guidelines over content that are maintained so as to maintain the sanctum of the medium and is not imposed legally.

it is just used to pressure people into making the sort of content that needs to be made according to the enforcer.

But those who defy are not liable to losses.

This is not the case in censorship when people are penalized for going against the set of guidelines and may even get criminal sentences

This has been going on for a long time in the country under the new age and in the world.

The Ones Who Walk Away from Omelas” is Ursula K. Le Guin's allegorical tale about a Utopian society in which Omelas' happiness is made possible by the sacrifice of one child for the sake of the group. In an allegory, many symbols and images are used in an attempt to illustrate universal truths about life.
