David Gerard writes: "Internet Brands bought Wikitravel.org in 2006, plastered it with ads and neglected it. After years, the Wikitravel community finally decided to fork under CC by-sa and move to Wikimedia. Internet Brands is now suing two of the unpaid volunteers for wanting to leave. The Wikimedia Foundation is seeking a declaratory judgement that you can actually fork a free-content project without permission. Internet Brands has a track record of scorched-earth litigation tactics."
