This is way off-base. The GPL neither wanted to not has been able to restrict commercial profit from the works it's been used with. You also imply GPL prevents corporate developers from using GPL'ed software, which is patently untrue. The GPL allows any person or organisation to take software and do absolutely anything they want with it, for themselves, without any obligation. The GPL might have come out of a non-commercial hobbyist/hacker culture, but it certainly doesn't impose either practice.
