And thank zot they are; gives the non-expert access to a Posix userland. And ports.
Of course, it is outrageous what they charge for the OS and the free upgrades! I can't count what I've spent in the years since, keeping my 2011 unit up-to-date.
Meanwhile, the BSD folks keep working away garnering support and contributions based on the quality and utility of the results, not enforced by licence terms.
GPL is great for stand-alone applications, but its tainting issues (hence the LGPL), make it a difficult choice for tightly integrated systems like kernels and OSs. I'm sure when the Hurd arrives, it'll all be fine.
