Well the VM Infrastructure can be opened up when the government takes on its debts for the investment. Then VM and BT can be on a level playing field.
The current FTTC investment also includes government subsidiary/incentive I believe, e.g. BDUK Rural Broadband, trouble is there is only BT left now after Fujitsu withdrew. Couple of useful articles below although this is in danger of getting away from what this thread is about.
