Thanks to doublec, there are now distributed censorship-resistant Wikipedia mirrors in Freenet [1]: Distributed Wikipedia Mirrors in Freenet [2]
The current largest mirror is the Simple English Wikipedia (the obvious choice to fight censorship worldwide: it is readable with basic english skills).
With this mirror, information from Wikipedia can be accessed in high-censorship countries:
freenet:USK@m79AuzYDr-PLZ9kVaRhrgza45joVCrQmU9Er7ikdeRI,1mtRcpsTNBiIHOtPRLiJKDb1Al4sJn4ulKcZC5qHrFQ,AQACAAE/simple-wikipedia/0/
To access the site, install Freenet from https://freenetproject.org [1] (or get the installer from someone). If you run it on the default port, you can access the mirror anonymously via the following link:

To test this without installing Freenet, see
