(Long) distance communications, just like public roads, breathable air, potable drinking water and so on do not fit into a "free market economy" paradigm.
They simply don't fulfill the basic requirements that make the "market" idea work.
Specifically, a free market needs goods from different suppliers to be easily interchangeable. You cannot sensibly build multiple roads parallel to each other, or have multiple water pipes installed and you have only one airway to breath through.
