Those higher speed PON can actually be a lot more expensive to deploy right now, though they eventually come down with time of course. Deploying active direct fiber everywhere would be quite the undertaking in terms of funding.
I agree though the goal should be to deploy fiber everywhere. I was just responding whether or not it's utilitarian to roll out the higher speeds like 7G while waiting for that - it is at it costs next to $0 on the infrastructure side for the areas already having the fiber independent of resources we dump into rolling out more fiber.
