First off, IANAL, but I've been paying a mildly interested amount of attention to GPL issues for, golly, 30 years at least (I know, I'm one of those old dudes), and I'll also say upfront that I am NOT a fan of the GPL, I think the MIT license got it correct, if you want your code to be used by as many organizations and/or people, or whatever, as possible, then that's the license to use. As far as my limited understanding extends, and what others who are far more knowledgeable than me, have always said, is that the GPL is "infectious," in that if you (if "you" are a company or an organization or whatever) use GPL code in your closed source product, you have violated the GPL. Seems pretty simple to me. But with all the arguing and legal wrangling, as far as I know, the FSF has never been able to extract vast fortunes from corporate GPL violators. In my humble and probably not all that knowledgeable opinion, if there's UNIX-like code that would contribute substantially to a closed source product, the BSD code is probably at least as good as the GNU code, if not better. Okay, dismounting my high-horse now...
