Have you noticed how Maduro supporters censor the Wikipedia article on Nicolás Maduro? Nothing, absolutely nothing that could be considered negative for Maduro can be allowed there. If you read articles about well-known politicians - Obama or Putin, Pinera or Mujica - you can see a lot of information that can be constructed as unfavourable. Maduro's Wikipedia article, on the other hand, is a sanitized article that could very well be placed in the government's official sites.
This is not what an encyclopaedia should be. The article goes completely against the spirit of Wikipedia. But then: a lot of Maduro supporters can afford to spend more time becoming administrators of the English and Spanish Wikipedia. Hugo Chávez's article was never censored as Maduro's.
