kazinator was correct that saying one product made it proves nothing about overall effectiveness of its attributes. That's unscientific. If we're using uptake and maintenance as criteria, we might start with the venerable Sourceforge to see what percentage of projects go anywhere or get maintained under various licenses (esp GPL). Compare that to proprietary while we're at it. I predict results aren't going to look good for GPL's success rate and that's without a financial requirement.
Far as compilers, proprietary are winning out in terms of longevity, it's a select few proprietary vs GCC in terms of performance, GCC in uptake, LLVM with decent performance/uptake, and some others with intended academic uptake. So far, that's barely any GPL, one industrial BSD, quite a few academic (MIT/BSD licensed), and many proprietary. Apples to apples, GCC is barely special except in what it offers for free and how hard it is to extend. That's why LLVM was designed and why Apple built on it, among other companies and OSS-loving academics. After a mere market survey, GCC suddenly doesn't look amazing.
Now what's your thoughts on GPL getting the only development when I bring up Apache, BIND, FreeBSD, Sendmail, and so on? Plenty get development. Success stories, just like GPL, still have little to do with copyleft of the license and a lot to do with community or resources.
