Mine comes from experience in a world of hardware and physical products that gives me a greater affinity for the business model of hardware companies than "open source friendly" advertising giants. I have a fascination with the war of words free software adherents wage against nvidia - the company could give out candy to children and it would get criticized because Linus gave them the finger.
I'll also admit that I am entertained by the no true scotsman squirming that occurs when I point at things that nvidia has done that don't support the story that it is the evil empire.
