"the telco giant had declined to invest its own money, because those areas were not considered commercially viable."
To be fair, it's not just the 'telco giant' that reckoned the areas weren't commercially viable. I didn't see a queue of competitors lining up to do the work without subsidy, even in many areas where BT HAD installed fibre without government dosh. At least this way, most of us, eventually, will get a fairly reasonable service. Just don't hold your breath for the 500Mbps rollout!
