You may be thinking about the copper land land regulations. Back when, the government subsidized Ma Bell to bring copper lines to everyone. As such, Ma Bell, and then the 'baby bells', were forced to share the infrastructure. Verizon made the case that if they were to build out all new infrastructure (fiber), on their dollar, they shouldn't have to share it. The government agreed, if they took it all the way to the door. This is why Verizon chose to install all the way to the door and then disconnects your copper lines. So the sharing of the infrastructure is what is no longer regulated on an all fiber network.
