In some EU countries, Australia, new Zealand, and the UK those initial networks were rolled out as government departments so the government did not expect an initial return.
Fun thing, the Australian and UK telephone networks were rolled out under the direction of the postal services before being split off to their own departments.
Since the 80s most western governments are trying to sell off assets under the guise of Privation so we are very unlikely to see another initiative like it. There have been exceptions like the Australian National Broadband Network but those are planned to be broken up and sold again anyway.
