> The anarchy stuff is just marketing nonsense.
With this sentence you're implying that Wikipedians want the public to believe that Wikipedia is anarchic, but this is incorrect, see: https://en.wikipedia.org/wiki/Wikipedia:What_Wikipedia_is_no...
The link is a Wikipedia policy, so pretty much as official as it gets. The sad truth is that Wikipedia policies, guidelines, etc are mostly irrelevant to the functioning of Wikipedia.
The real de facto reality of how Wikipedia operates is that it's a complicated system with most decisions being made being local to only a single or a few articles. Furthermore, nothing is set in stone at Wikipedia, be it content or policy, they all change with the whims of the editors currently active at the relevant place and time. Which is also why policy is mostly powerless.
