afaik, they just bought out the accounts that the likes of TT and Sky didn't want any more because they weren't profitable and there was no way they could do the cheap deals if they didnt have a presence at that particular exchange to do MPF LLU.
The money these days is in hiking up the price of telephony to subsidise DSL. TT & Sky don't use WLR preferring to go full metallic path and install their own kit so they have both phone & DSL.
Daisy/Fleur do use WLR which means they can provide at all exchanges where BTw offers a service. Because they now own Murphx, this means they can provision over their own Core, so what they will likely be doing is hooking in at the Core Node Interconnects using
WBC to offset their costs.
Other BTw based ISPs such as Plusnet, IDnet etc, use
shared WMBC which uses the BTw Core.
Although they do own their own core, Im afraid it doesn't mean anything more for the rural consumers as they rely on BTw to do the back-hauling to the exchange.
