Software products have near-zero marginal cost of production and distribution. Physical products have significant marginal cost of production and distribution.

Monopoly dynamics for ubiquitous products comes in large degree from the economies of scale across production and distribution. This allows larger companies to supply the same thing for less money. Even if you eliminated branding, you could not produce and supply a coca-cola can at the same price as coca-cola can :)

With software, you cannot get the same cost advantage through scale.
