If you think they are lying about this or are incorrect I'd suggest you contact Ofcom. BT also may want to know as all their advertising of their fixed rate services were based on this assumption.
That or BT may know more than your knowledge based on reading internet forums about their own network.
Regarding your other comments I never said anything about the quality or otherwise of BT's network so all I can say to that is (hate this word but) whatever - I have had the pleasure of troubleshooting a lot of BT copper related issues on DSL lines so I assume nothing.
Anyway sorry to disturb your now cross-thread rant. BT are rubbish, ADSL is rubbish, worst network in the world, crap copper everywhere gone green, BT intentionally make lines longer, etc, etc.
If you want to see crap lines go check out some other countries such as USA and Canada with all overhead loading coiled and bridge tapped gack, or Australia with a fixed very strict distance and very low speed DSL deal.

When and where have BT stated they use 0.5mm copper for all their lines? I have heard from numerous BT employees that the copper used varies from location to location, the unluckiest will have poor aluminium cable and the luckiest will have thicker good quality copper cabling, so straight off when you mention 0.5mm copper cable I am already seeing question marks, what % of lines use 0.5? if no % is defined then thats something else that puts that into dispute. I also suspect specs on paper the ones you have written will generally be worse then real experience due to corrosion and ageing of the copper.
