For anyone new to the distinction, Internet Brands bought Wikitravel and the community didn't like that, so they forked to Wikivoyage. IB tried suing Wikivoyage for this despite it being allowed under the content license -- either IB didn't do their due diligence on the license of the content they bought, or they thought they could bully the community fork through the cost of fighting it alone. It was eventually thrown out of court, as it should have been.

Wikivoyage is now hosted by Wikimedia, the same nonprofit that hosts Wikipedia.
