Part of this is the much-hated reference requirement -- all facts in a Wikipedia page must have an external source to back them up. This rule alone causes a huge amount of strife among those who don't understand
It causes a huge amount of strife because it's yet another policy that's easily manipulated by people with no common sense.
For a long time the article on Bitcoin stated outright that it was a ponzi scheme, despite that Wikipedia's own article on Ponzi schemes had a list of requirements which Bitcoin obviously did not meet. Attempting to get this fixed was a kafkaesque nightmare due to someone camping on the page and immediately reverting any change that removed or even just qualified this statement. The reason: the statement had "citations" which turned out to be (a) someone's blog, and (b) an article in The Register, that well known bastion of reasoned and careful analysis.
Wikipedia is a project that manages to work in spite of the absurd management and crazy policies, because the idea of a global encyclopedia is such a compelling one. But it badly, badly, badly needs to be forked by people who find a way to run it better.
