It's not a case of told you so.
"The chorus of "FTTC is not enough" have done their work. Now OR have got a means of getting a price increase past OFCOM"
You're being disingenuous, stating full fibre is all about headline speeds. It isn't.
The point is FTTC and Pointless G.fast don't help anyone with flakey lines (aka. low-level pump noise - industrial areas), longer copper lines (500m / 250m as the crow flies), fairly short aluminium lines regards 100Mbps+ Ultrafast services, the only way ultrafast services can be cost-effectively achieved is using full fibre on anything other than multi-dwelling properties, using a single technology deployment.
Edinburgh/Glasgow tenements are probably the best type of use case (if any) for Pointless G.fast, but it's niche in the scheme of things.
Fault finding G.fast / firmware incompatibilities / redundant standards within the vectored VDSL2 side of the copper network will become more and more difficult to fault find (aswell as getting ADSL switched off), as this technology ages / some kit is upgraded / some kit remains non-upgradeable. It becomes a can of worms to fault find going forward.
There are so many additional advantages to using full fibre.
Openreach know this. BT-Group know this, Ofcom know this. It's not a case of told you so.
It's disingenuous to start saying this is reluctantly happening as a result of loudmouths banging the need for (just) more speed, if there wasn't a business case for full fibre in terms of lower maintenance costs/better reliability of the network (with less pressure of BT's absolutely disinterested abysmal Customer Service) or Political pressure on them to 'shape up' or be moved to one side (the bloated BT drunk blocking the doorway for those attempting trying to get to the full fibre bar) - I very much doubt this would be happening.
The penny dropped for BT when there were no more subsidies on the table for further copper carcass upgrades to their network. They knew they needed to look again at full fibre, even though they'd used the line "Copper is cheap, Fibre is expensive" to justify their bias regards decisons towards further copper investment.
And cautious as ever, it hasn't happened yet.
