I'd argue that history shows otherwise. GPLv3, with its increased restrictions, proved a bridge too far for a lot of projects, to the detriment of everyone. Apple, the FreeBSD project, the OpenBSD project, etc have all put in efforts to divest themselves of GPL encumbered code because it increased the costs of using the software. Because the wording of things like the patent clauses were so questionable, it became much cheaper in terms of lawyer time, etc, to either use older software that was still under GPLv2, or to use software using less-encumbered licenses, like BSD and MIT. That balding middle manager needs to make sure that that license is acceptable by his boss, by the people in the legal department, etc. For example, an innocuous throwaway line of a program that can only be used for "good, not evil," ends up needing to get the lawyers involved for clarification and special waivers ( http://dev.hasenj.org/post/3272592502/ibm-and-its-minions http://dev.hasenj.org/post/3272592502/ibm-and-its-minions ). If the internal costs of using an encumbered program are too great, then chances are, it just won't get used; the company will either write their own version, or use a commmercial variant.
