Yes H & I expect there will be of folk get railroaded for that, however....

Here in the UK, BT have completely shafted & Bastardized the Fibre concept. Still using shit copper with some Aluminium in some areas to get to the Fibre cabinets. (FTTC) Lots of these people will probably suffer bad 4K streaming unless they have a short pair of wires (250m) to the Fibre Cab.
However, a really sweet pair of wires over 750m may still do well, depending on other local residents speeds on the same cable as yourself. (Cross-talk affects & effects your speed)

It really pisses me off with BT adapting a shit wired network from the GPO days to run on a partial Fibre infrastructure that is lagged to death with Interleaving applied to your service. - You can only stack shit so high....
