Re: FTTP is cheap.
"There's no monopoly in the UK, anyone can set up a network and sell service to the public."
Nonsense, there are huge impediments to anyone wanting to roll out a physical network, whether it's the permission for street works, obtaining wayleaves, or the cost of access to BT's ducts and poles (let alone building your own). BT has significant historic structural and regulatory advantages over any incoming network provider, which is why VM still struggles under the inherited debt burdens of the individual local cable providers from the 80s and 90s, and why altnets face such struggles today.
