Free software made cheap, network centric computing feasible. This led from a model where the user ran their applications (open or closed) on their machines to one which turned the user's machine into a dumb terminal to access the network. This resulted in defacto loss of user privacy and control.
In a world where Windows was dominant and you had to pay a per cpu licensing fee, would companies be trying to put everything on the web, or would they create more apps that ran locally with some network based syncing? It would have been a smart computer, dumb network world instead of the dumb computer, smart network world we have now.
One of the great ironies of computing is how free software in its quest to enable user freedom actually enabled a world with less defacto user freedom than before.
