It's a Jurassic Park point, really: life will find a way. Free software beat the world already, and it really strains logic to argue that that only happened because of a giant phonebook filled with special advantages for every individual piece. The much simpler theory is that it was clearly going to happen regardless.

Linux on whitebox PCs was dominant in the early internet world for pure cost reasons, long before any corporate names got behind it, and that leveraged it into datacenter environments where it became clear people were willing to pay real money. Red Hat's IPO was well in the past and Google had launched on custom Linux motherboards long, long before Oracle or IBM got serious about the OS.
