I think, what the next GPL needs is too use of the long breath of the free software movement. I mean, the ability of a GPL Project to be used in closed-source and after a given time frame (5 years) the whole resulting code-base must be re-released into open source. Many software products contain GPL-Licensend content, and these "quick-and-dirty" predecessor-software is abandoned once the producer reaches a certain "Lets-Refactor-it-out" success. The GPL could become a breaker of the infinite copyright and a driver of inventions, while at the same time providing the major advantages closed source holds for a limited time.
