From my reading of the article. Stardock purchased some rights to the franchise. Then the original authors released a new game in the series. Stardock then sued the original authors as they believe they now own the franchise. The original authors are now counter suing. Edit: after reading https://www.stardock.com/games/starcontrol/article/487690/qa-regarding-star-control-and-paul-and-fred https://www.stardock.com/games/starcontrol/article/487690/qa... it seems Stardock only sued in response to take down notices. Second Edit: after reading https://www.dogarandkazon.com/ https://www.dogarandkazon.com/ I have no idea who sued who first. Both accounts don't seem to agree. Third Edit: Watch the video in cdumler's comment it gives a very good summary from the courts.
