Imagine how much room there would be if we broke up Facebook, Apple, Amazon, Microsoft and Google. Having another decade of cut-throat tech competition might be good for us.
The point is to place a cap on the scale of organizations, enabling multiple smaller entities to provide the same services as the original larger organization, but with increased competition at all levels because the large organization's bloat and efficiencies of scale are eliminated. Part of the goal here is to remove efficiencies of scale because they suppress widespread employment as well as opportunity for individual skills advancement. Large scale providers eliminate employment opportunities and the skills advancement that goes with them simply because their scale eliminates any other players that could exist in the market.
