IANAL. I'm not a GPL expert. But here's my reasoning: 1. Code written under the GPL is value created for public consumption. VMWare is violating the spirit of reciprocity by benefiting from that value, creating more value on top of it, then not releasing their additions for everyone to benefit. So it's not about Christoph's benefit, nor the company's. It's about our benefit as the people not involved directly in that transaction. 2. I imagine copyright gets really hairy if you write something, someone comes along and modifies it over a period of a year or two, then claims ownership. I imagine the GPL helps clear that sort of thing up as well.
