Technically-adept people (like me and you) know how to get around such things using proxies, but the average citizen doesn't. Plus, I'd expect nations enacting censorship to outlaw the use of proxies too, or to at least make the use of one a suspicious act meriting closer scrutiny.
Anybody who wants to read it online can just use one of a number of web proxies... or if that's too hard, they can use an online translation service as a proxy!
Just set your online translator to translate the webpage you want to read from say, Korean to English. Since there is nothing in Korean on the page, it translates nothing, but works as a proxy.
Of course, it might just be easier to find a free web proxy by searching Google, but this way makes you feel more clever.
