[$] Making the GPL more scary

For some years now, one has not had to look far to find articles
proclaiming the demise of the GNU General Public License. That license, we
are told, is too frightening for many businesses, which prefer to use
software under the far weaker permissive class of license. But there is a
business model that is based on the allegedly scary nature of
the GPL, and there are those who would like to make it more lucrative; the
only problem is that the GPL isn't quite scary enough yet.
