As far as actually being copper. All new replacement wire is steel with copper clad. Its not copper. So you need to get up to date.
Also if they would really install fiber that would be one thing but that's not what they want to do.
What they want to do is install fiber in the cities and abandoned all rural areas and towns. In those areas they would force everyone into cellular service with data caps. Making much more money because land lines are regulated and the cell networks are not.
They don't want to sell the rural areas to someone that might upgrade them to fiber they want to shut them down.
Under the current law they must serve everyone and not abandoned anyone. If the plan is to serve everyone with fiber that's great but that's not the plan.
This is the Grubber plan the FCC says the voters are stupid we will just lie to them. We will call it one thing and do another.
What they are really discussing is shutting down land lines to rural areas. It has nothing to do with converting to fiber. All the cities are already converted to fiber.
