Isn't the real question, "How do so many small and medium sized telcos manage to bring all-fiber to their customers, while the big boys seem to have such a hard time doing it for their smaller metro area customers?"
One answer to that question is that that some small telcos have been allowed to replace their copper infrastructure with fiber while the large telcos have had to do "last mile" fiber overbuilds except for "greenfields" or disaster replacement.
