Originally, this was designed as the title of this section suggests --- as
a last ditch effort to make sure that freedom was upheld. However, in
modern times, it has come to give much more. Now that the body of GPL'ed
software is so large, patent holders who would want to be distributors of
GPL'ed software have a tough choice. They must choose between avoiding
distribution of GPL'ed software that exercises the teachings of their
patents, or grant a royalty-free, irrevocable, non-exclusive license to
those patents. Many companies, including IBM, the largest patent holder
in the world, have chosen the latter.
Thus, \S 7 is rarely gives software death by stopping its distribution.
Instead, it is inspiring patent holders to share their patents in the same
freedom-defending way that they share their copyrighted works.
