If the same company that built the road is the company that eagerly sells tanks to all comers, promising them zero traffic wait time, and refuses to let the tanks go on any other road, then the party to blame is the company that built the road.
This is what AT&T does. They claim they have the fastest network. They negotiated an exclusive iPhone deal so the load can't be spread. They sell and market iPhones as much as they can. They promise unlimited bandwidth. etc.
This.
