Don't get me wrong, I love Linux and loved FreeBSD back when it was more easy to choose... But I do think the 'free UNIX' movement has had unintended consequences like the demise of Sun, and perhaps now also this exposing of a failure in what was a desktop class chip architecture that was elevated to server usage.
Everything has a cost is all I'm saying.
Honestly, back when Linux started getting momentum, RMS' GNU/Linux argument had merit. Most of the stuff people where running on top of Linux, never mind using to develop Linux, came from the GNU project.
