It's a profitable service, like the post office was before they were sabotaged with pension requirements. Users would still be the ones paying, but a greater portion of the profits could go to the workers, and the remainder would go to public projects and other government expenses. That would be preferable to the services being used to continue drawing wealth and power from the working classes to the already wealthy and powerful. The only time it might end up subsidized is if it had to be commandeered for a public use purpose like delivery of food and living essentials during a disease outbreak.
