It might have been better if they'd given up on G.FAST when it became clear that it wasn't going to work as a cheap and cheerful 'not spot' fix. Continuing to assist with development and then deploy it has led to short term coverage gains at a time when most people don't really want it. By the time demand for something better than FTTC is ramping up it'll be time to pull the G.FAST kit out and move to GPON fibre. This is because the reach of G.FAST is naff (probably less than a third of lines on a typical cabinet can see any benefit). So to get decent coverage of 'something better than FTTC' means FTTP at which point the G.FAST kit becomes obsolete.
Short term thinking to appease the bean counters :-/
