Someone at BT has worked out that this time around the Ofcom review is going to be different & hit the panic button.
Unfortunately its the same old nonsense you get from all monopolists - "don't be nasty to us, we'll do better in future, honest guv".
BT had their chance and have proven time & again that they will not "behave" until someone waves the big stick again. Enough waving the big stick - this time hit them with it and force them to float Openreach off as a totally seperate company.
