I'm also surprised why there arent any community websites or groups wanting better broadband for their area. There seems to be all kinds of facebook groups for everything, but Internet Fibre/ADSL stuff. It's odd.
Now you mention it youre right. Campaigning for DSL broadband (as opposed to dial up) used to be a really big thing.
Same with FTTC there was a lot of interest in it and arequite a few groups trying to get vdsl to certain areas.
I dont know if it is due to the fact that the majority are happy with fttc /want fttc or that fttp may be more than most people want to budget for.
In a similar vein though, you never seem to hear much about any campaigning for cable. I think Ignition tried to approach VM for his estate, but Ive never really heard about any more from anyone else.
Obviously though there are sites like B4RN/hyperoptic, but nothing specifically BT related that Im aware of.
