I'm not sure why this is getting downvoted, because even Wikipedia acknowledges the issues with its contributor community.

Years ago I had a friend who worked for Wikimedia Foundation and was very enthusiastic about it. That optimism didn't last for long. He left after a few years citing WF's messaging style of "holding the content hostage" during fundraising drives and the established, exclusive contributor community that, more often than not, would drive away new contributors with snippy responses and arcane editing rules.
