Lets make this a pro and contra
Against censorship:
There has been some research done in capitalist countries that suggests that censorship has a tendency to silence poor people.
The Soviets had some censorship (although not to the degree that anti-communist propaganda says) and it did not prevent the revisionism from spreading.
A part of the Soviet information landscape was, that it was very scientifically accurate and virtually devoid of scams, there were no scammers trying to sell you free-energy devices or miracle-cure juice. Pyramid scams did not exist and nobody was pretending to be a medium that could contact your dead relatives. And the effect was that Soviet society had no mental defenses against bullshitters. People got accustomed to sanitized information and after the Soviet dissolution when the sanatisation disappeared they got duped by ALL the bullshit.
For censorship:
I think that censoring might actually have a singular useful application. Censoring News about terror attacks might be reasonable. Terrorism as a political strategy would be completely ineffective if there was no medium to spread the fear.
Some considerations:
My conclusion is that censorship is largely not worth it.
If you want to extinguish scams, you need to hire "white-hat" scam artists that do scam routines but instead of screwing people over they just cause embarrassment. That should be enough to cultivate mental defenses and dry out the pool of gullibility.
