If the GPL's progress is imeded by developers just accepting this like sheep, then GPLed software will NOT be used in business. And business is where I use most software. Proprietary crap is what makes my life miserable; having crap changes forced on me by vendors with a marketing agenda, and NOT being able to fix problems with the software as I encounter them. GPL(v2) software offered a way out - v3 cuts off that hope. If my interpretation of it is correct, anyway, and being that you simply accept that interpretation, I must believe that it's a fair one.
Let's put it this way - I _DO_ do due diligence, and with GPL3, there is far less advantage to using GPLed software. The source becomes useless to business. Unless they want to be a software publisher - and, guess what? That ISN'T what most businesses want to do.
