While it's obvious that some information is numerically greater than no information, it's not obvious that a censored flow of information makes anyone's life better than the alternatives.
When the information flow is all-or-nothing (either you get the full uncensored fire-hose, or you get nothing and whole sites/services are blocked due to censorship), the citizen at least knows they're being censored, and then the ball is in the citizens' court as to whether they want to advocate for a reform of that censorship.
When censorship is selective (e.g. "You can read all of Wikipedia, except for whichever articles the government doesn't currently like this week/year"), citizens are mostly going to be unaware of what they're missing and how selective their worldview might actually be. This is very insidious, stealthy, and difficult for a citizenry to be aware of and politically revolt against, especially given there will commonly be no transparency or oversight as to the banned-topic list at any given moment.
Personally, one of my stronger meta-values is that any state which stands on the side of forcibly hiding information from its citizens is on the wrong side of history and ethics. If you can only defend your government to its citizens by lying to them, there's clearly something wrong with what you're doing.
