Hah! You are delusional. To be specific, it's obvious he meant virtualbox + the roughtly 2 other less commonly used free desktop virtualization softwares.

Let's spell out the obvious: People, like me, use virtualbox etc. for free instead of paying for vmware fusion / workstation. If the free products didn't exist, vmware would be making much much more money on licenses for worstation etc, and developers would still be getting paid to work on the vmware products.
