It may be possible that Sky & TalkTalk's UFO project may work much differently to Openreach's systems thus the reason for not using Openreach and maybe they have so suprises up there sleeves...
As far as rollout's go they do seem to make people mad, with situations like your friends, however it may of been a case where your friends line to the exchange may not have ducting for significan't parts of the line which lead to him getting FTTC rather than FTTP...
Also last time I looked all in one PCP and FTTC DSLAM had a limited number of ports for use, and it may have worked more conveinient to run FTTP to the other addresses further from the exchange due to them having ducting availble to use... they're could of also been restrictions on where the FTTC DSLAM could be placed and that may have cost more to divert the network and/or dig roads Ect....
I live in a newly converted office building in the centre of Crawely....we're 400-500 metres (Cable length) from the BDUK Funded DSLAM, getting connected was a nightmare due to Openreach not updating systems correctly and for failing to complete neccesary work earlier in December...
I was so annoyed that I wanted to go back to Virgin Media and just deal with the utilisation issues as they came, however most people in the block seemed to be more interested in Sky than Virgin and enough people didn't register interest it seems...
Annoying too, as Virgin's Fibre and Coaxial networks run 2 metres from the front of the building, they may still add the building to the network though a plan will need to be made and apporved by buldings owners/management...
The annoyance with a building like mine and the other 184 apartment building currently being finshed off next is that they could easily have fibre rolled out in them, but Openreach as you say either won't benefite from it or too busy to do it... though it don't help that developers don't think about it too.
I approached Hyperoptic but they wheren't interested as I was enquiring about my building of 24 and I think they need the developers to contacts them at ealry stages to get something started... (installing POP)
The other thing that will be very annoying soon is that the 184 apartment being built will be connecting to my BDUK funded PCP.... it's only a 96 port cab and is already connecting the busy high streets and other flats and buildings... so most those residents will no doubt be stuck with ADSL at around 12Mb/s
