License: GPL-2+ Comment: I've erred on the side of caution, but this may be a case where the author has attributed copyright to the FSF, because README:L48-50 read as follows: AUTHOR Yoshiki Kurihara Copyright (C) 2010 by Free Software Foundation, Inc. . Conversely, yaml-mode.el:L3 asserts that Yoshiki Kurihara is the only copyright holder.
