Lowe pulled the plug on the auctions, according to Britton Mathews of the Sierra Gamers Facebook group, after receiving a letter from a law firm hired by Activision demanding that he take them down. Interestingly, Activision acknowledged in the letter that it does not own the rights to the Leisure Suit Larry IP, but said that the source code probably contains "shared code" that's also present in the King's Quest and Space Quest games, which it does own. That was apparently enough to spur the takedown notice.
