Re: This sort of crap
"Why would you invest in new network expansion when you then have to allow your own competitors to undercut you using the cables you just installed?"
You're still selling those customers a service, and making a profit on it, either way - you just might have to sell through a middleman for some of them, instead of being able to force them all to buy directly.
Personally, I'd prefer Openreach to be a genuinely separate company, with proper independent accounting - which, after all, is what BT claim their structure already delivers, so they have nothing to complain about there.
Right now, BT are offering an FTTC package for £7.50 per month. The wholesale price for the connection between your home and the exchange alone is £8.28 per month. So, do you think the bandwidth from the exchange to the Internet, plus authentication, DNS etc genuinely costs them less than minus a pound per month, or are they abusing the monopoly to undercut their rivals? (Oh, they include their BT Sport TV channel for that negative amount per month too...)
