I could have sworn Fargo got the rights a few years before he ran the Kickstarter, but looking it up I came across this:
June 13, 2003: Brian Fargo and his new game company, inXile, acquire the rights to Wasteland with the United States Patent Office. Soon after, Mr. Fargo shows up at Snake Squeezins to ask for comments about the game from its loyal fans. He notes the reason he didn't get the rights sooner was that Electronic Arts was sitting on them. When they expired, Konami grabbed it for use with their Yu-Gi-Oh series, but they were kind enough to let him have the trademark back.
So it would've been they got Wasteland from EA the year before Bethesda snatched up Fallout. Guess it turns out that Fargo was the one just sitting on Wasteland for years.
