I agree that the analogue with feudalism is stretched, and I can't help thinking that the Techno-Feudalism idea was chosen mostly for the associations that it brings with it: dark ages, lords and peasantry, serfdom and war, etc.

I don't get why instead we shouldn't compare the current times with the early stages of the industrial revolution, when factory owners exploited masses of workers who could only choose between accepting whatever terms the factory offered, or starving. It would also be a more productive metaphor, because while feudalism spontaneously disappeared with the birth of an entirely new social order, the evils of the early industrial revolution were successfully defeated with collective action and progressive legislation. Which is what we probably need now.
