You said, it couldn't be commercialized. GPL prevents 
commercialization, if the latter won't happen anyway, GPL doesn't 
give you anything.
I did that, but sent a patch to the developer, diff -ur doesn't 
hurt in the least. Though the tool is only used by developers, no 
redistribution required, so GPL wouldn't prevent from doing 
private changes and still benefit from them (the tool provided a 
very important feature absent in a commercial analog, and I added 
3 more more cool features).
