I work in tech. Some would lose, but others would win. We spend more and more every year on services. The software isn't entirely FOSS, but the licensing cost is often trivial compared to the costs to implement and maintain. For instance, we use WordPress for our website. We give thousands every year to our web designers while spending 0 on the software. The big software we use, that we spend hundreds of thousands yearly on, is moving in the same direction. I suspect they will go FOSS in the next decade, and focus on hosting/professional services.
