The bit about the drop wire is being mis-used I believe...
The full consultation talks about problems with some drop wire from poles, i.e. adding another providers fibre drop would require a new pole and thus be expensive, so as part of the consultation it is looking at an option so Openreach will replace existing drop and the consultation does mention the copper/fibre combo drop wires that exist, i.e. small fibre tube and copper pair in one cable.
Of course for this to happen, the people asking for the drop wire swap would also have to be offering fibre across the rest of the network too. So its not about TalkTalk being able to put in a request for a fibre drop and thus forcing Openreach to install fibre all the way - the all the way part would be achieved via the PIA pole/duct sharing.
The Daily Mail article is so littered with mistakes and confusion that I'd expect Ofcom to be phoning them up for a correction or too.
