Any production system has the same issues, they're usually called overhead or in some cases agency costs. This is captured well in the marginal productivity of labor: the returns on adding more labor decline as you add more labor. Talking about actual economies of scale, software has massive economies of scale. The marginal cost of serving one additional copy of software (in the old "software as a product" way) is close to zero.
