In a technical or structural sense, the censorship regime's aim is not to censor or to oppress, but to rule. That's why the authorities can never be labeled as guilty of disinformation.
Not when they lied about Hunter Biden's laptops, not when they claimed that the lab leak was a racist conspiracy, not when they said that vaccines stopped transmission of the novel coronavirus.
Disinformation, now and for all time, is whatever they say it is. That is not a sign that the concept is being misused or corrupted; it is the precise functioning of a totalitarian system.
