From a commercial standpoint it's irrelevant what the license "intends." All that matters is what the legal department thinks will happen in the worst case, and for GPLv2 or v3 the "worst case" is all that proprietary software that the company wrote on top of it is now publicly available for free to any end-user. The claim that GPLv3 is the future of open source licenses is laughable. There are going to be a few idealists licensing their software using GPLv3 but that software won't gain significant traction in any sort of commercial setting, outside of a few exceptions. Just take a look at the software libraries that get widespread use today: the vast, vast majority of it is Apache-, MIT-, or CC-licensed. GPLv3 is going to end up being a historical footnote at some point, because economics trumps ideology every time.
