I submitted the proposal to be able to eliminate certain parts of the articles in certain countries, where the local governments find those parts illegal: https://bugzilla.wikimedia.org/show_bug.cgi?id=62231 But it got rejected, and I am not sure I am clear why.
The problem is that there are countries that lack the freedom of speech (most of the countries), and some of them get very aggressive about banning materials that most reasonable people wouldn't find objectionable. The very recent example, provided in the bug report above, is banning of any references of Adolf Hitler's book "Mein Kampf" in Russia. While this case may seem not as important, but I don't see why users outside Russia should be affected by such decision, when they may not even support any decisions or values of the said government. Yet, everybody's version of wikipedia page is affected, and materials are hidden.
My suggestion, if implemented, would allow to hide certain parts of the articles in the country (or area) of jurisdiction of the corresponding court, while allowing users not living there to still see the original version.
If such governments get their way in banning materials globally, this will effectively make wikipedia biased, and reflecting various POVs of various courts, which has never been intended by wikipedia.
