It's not so much Wikipedia is aligned "with" anyone (in a favoritist sense) but that they are on good terms with them. Wikipedia lists a few of the internationals here, note how Communist internationals take up the bulk of internationals, some which share countries. The two most relevant ones are this and this one which star North Korea. Having never heard of a slant towards the WPK before yesterday, how this might be still piques my curiosity given the internationals seem fine, and the only thing that comes to my mind is how North Korea has, let's just say a digital reputation.
