Installing software from a USB drive is within the reach of most normal teens and young adults in the developing world. So, sneakernet -> IPFS -> Wikipedia is a viable path so long as blocking the IPFS protocol, over all reasonable transports, is hard enough to do.
Responding to 0xCPM (sibling comment). IPFS was not designed to hide the sources but thanks to versatility of transports (you can ever run it on cjdns or mesh network) and possibility of using it offline it is not easy to censor.
