I think a “free market” has to retain some degree of competition and choice. Companies above a certain size (of capitalization) or with natural anti-competitive elements (like network effects) or with ownership of multiple sides of a market or with massive patent war cheats all impede competition. They move the free market away from a competition driven incentive to something more stagnant that can discourage entrepreneurial competitive innovation.
