Ofcom spotted failings
No they didn't. They spotted the fact that Openreach and BT are the same company and naturally work well together, given they're the same bloody company.
i've said it before, and got downvoted. It will happen again, but it's still true. If these other companies like sky etc want 'free rein' on the network, they need to actually bloody invest in it. BT are the only company to have built the dang thing so they get preferential treatment, I see NO issue other than ofcom being moronic
