If you talk to BT engineers you'll know fibre has been around for a long time and is fitted around large parts of the country already. I was on FTTC back in the early 00's on an affluent new build estate but had a capped broadband speed to 2mb to maintain the charade along with packet filtering. Besides squeezing every last ounce of revenue out of the copper a form of planned obsolescence, the Govt also needs massive storage capabilities in order to spy on everyone. Its just a charade being played out by some arms of the Govt masquerading as business in this case BTOpenreach much like the CIA have invested in tech companies in the US to further military intelligence. Its called Bread & Circuses.
