ISPs and telecoms are natural monopolies. The state owning them would probably improve the options many people have access to. Also state owned does not have to mean it is owned by a federal or even state government. It can be owned by smaller units of organization. Furthermore there can be vendoring out of the parts that a private market is more competitive for (such as equipment).
