Wasn't Verizon given billions in subsidies for FTTH (which they installed on the east and west coast, the most profitable areas) and then sold off vast areas they didn't touch to companies like Frontier?
[1] When you build an income-producing capital asset like copper wire in the ground, you can’t deduct the cost from your revenues immediately for tax purposes, like you can with say employee salaries. Instead, you gradually deduct the capital cost over the income-producing life of the asset. If the government allowes you to depreciate an asset faster than the value of the asset actually drops, that nets you some tax benefit due to the time value of money. On the other hand, if the accelerated depreciation reflects the fact that certain types of assets depreciate quicker, then it will result in the correct amount of taxes being paid. For example IT equipment in data centers can generally be written off immediately—unlike wires in the the ground it’s pretty much worthless after a few years.
