This page aims to list all ongoing and past Internet censorships that are affect(ing/ed/ive?) to any Wikimedia Foundation wiki projects.
Opinion at the WSIS
The argument that Jimbo put forward in his talk in Tunis at the World Summit on the Information Society can be summarized as follows:
1. Wikipedia is neither critical nor supportive of the Chinese government. We are not a website for dissidents nor for government supporters. We are neutral. NPOV is non-negotiable. It is impossible to portray Wikipedia as anti-Chinese government unless the Chinese government wants to argue that neutral information is anti-Chinese government, and I don't think that's what they intend to say at all.
2. It isn't *just* that Chinese people cannot read any of Wikipedia, most of which is not about political or sensitive topics at all. It is that Chinese people are unable to *express* their views and culture in the Chinese Wikipedia or English Wikipedia or anywhere else, so long as Wikipedia is blocked. Since, I am told, the Chinese wikipedians tend to have more of a "mainland" view of things, as compared to Chinese living in Taiwan or Hong Kong, the ironic effect of the Chinese censorship is to censor the mainland perspective on world affairs.
It is fine to criticize the Chinese government for censorship of criticism. But my argument was not about that at all, since we are not critics of the Chinese government. My argument was that censoring Wikipedia in China is ironically censoring *the rest of the world* from hearing the voice of the Chinese people.
As indicated by activities of Wikimedians of Mainland China, as well as activities of users from Li Yi Bar of China, and the discovery of state-sponsored Internet propaganda from China among other countries, it have shown that Chinese government, as well as some citizens supporting the country's current regime, and also a few who have high information technology literacy, are able to bypass government restriction on internet browsing, enabling them to view and edit content of Wikipedia, despite the capacity to do so is not equal among citizens of the country. Thus, the NPOV principle of Wikimedian projects could face challenge with some of these contributors who attend the platform with specific objectives.

It has been confirmed that the biggest ISP provider in Venezuela, CANTV, has blocked all Wikipedias, all Spanish and Calatan other Wikimedia Projects, and blocking the usage of Spanish interface in other projects, to countermeasure sanctions from United States governments, and to protest supporters of "Guaidó temporary government" which is living in Colombia and Brazil border area with Venezuela. Also per some statements from IP users, even in cases that they may use other Wikimedia projects with English interface, under a special setting from CANTV, their IP address (and even ranges) are most likely neither from Venezuela nor from United States.
