There are a couple of others who own wires but really only in London (colt, forget the other one)
BT retail (the arm that sells to clients) has strict rules that forbid it from sharing with BT wholesale (the arm that sells to the other ISPs) so BT retail really can’t crush the competitors.. I don’t know the exact arrangement but they’re treated like any other ISP customer I believe
BT doesn't own our wires as such. OpenReach does (yes they were formally BT but spinned off).
BT or OpenReach - who cares? The important thing is functionality. I'd like to provide you with a novel telephony setup but the lack of ENUM means I am not able to do that.
