Moved ~/.local/share/steam. Ran steam. It deleted everything owned by user
Reminds me of a bug with the Myth II uninstaller immortalized by the following Penny Arcade cartoon:http://www.penny-arcade.com/comic/1999/01/06Basically, they called delete tree. If the user installed or moved the game to a different location, say, the root, it would delete tree away somebody's whole computer. Fun times.
