I do think that people should be on FTTP not FTTC
FTTC is fit for purpose and millions of UK homes are happily using it, to say 'people should be on FTTP' is pushing it not by a little but a lot.
Not really. Both ADSL2 and VDSL rollouts were stopgap technologies to bridge the transition of copper to fibre rather than any kind of solution for more than the short term. G.Fast thankfully was stopped in its tracks but even the fact they rolled some of it out shredded even the last bit of competence credibility OR and BT had. The fact BT and OR used it for so long was an error of Ofcom and the government not pressurising them and consumers not speaking up. OR still needs to die a horrible and painful death.
So yes, I agree with the OP that UK broadband has lagged severely behind as a result of egregious profiteering and downright inertia in OR, because we're only now in the transition where OR needed to be 10 years ago. But the physical network isn't the only issue, but also service standards have fallen tremendously over the last 10 years as well. The fact most ISPs, particularly alt nets, don't offer even basic things like static IPs or the use of PPPoE on an ethernet link is preposterous.
So there's an issue service side as well, as MTU, latency, contention and tunnelling rather than adopting more modern techniques such as EVPN per customer is drastically falling short of acceptable service levels too.
