They claim that " Copper " has an effect on speed, they claim basically that copper is only used by BT, and that the use of copper is only good for telephone calls.
But then we hear, this is not in the adverts by the way, that around 200m of copper is used in its broadband service.
You believe what you want, dont accuse me of having an agenda.

No insult was intended, but you are very quick to criticise VM, and very slow to mention the possibility that other ISPs also have problems.
My statement about Cable not being distance limited, and ADSL being distance limited isn't opinion. It is fact.
Copper (as used in Phone lines) *does* have an effect on speeds. Over miles (unless the cable is specifically designed for high bandwidth signals, as VM's network is). This is why the cable network backbone is fibre, and copper runs are relatively short (as you note, less than 200 metres)
Basically, the problem as I understand it is signal loss. Now, I know that there are networks that use miles of copper for high bandwidth applications, but these use specially designed cable , and use various techniques to minimise signal loss. This techniques are not practical to use on BT's network.
BT's phone network was not originally designed for data transfer, hence the fact there can be miles of cable between the user and the exchange, which is what slows data transfer.
Not that I am defending VM's publicity. While it doesn't explicitly state that the entire network is fibre (the ASA would leap on them if it did), it does very strongly imply that, which is wrong.
