You, sir, are an idiot.
The FTTH GPON was going to be deployed as 2.48Gbit downstream and 1.24Gbit upstream, servivcing 32 users. The contention ratios and upstream capabilities are freaking awesome.
By comparison the cheap FTTN proposal is being designed with 2GBit backhaul servicing 200 users. This sucks. Now, even if they upgraded to 2 x 10G fibres, you are still heavily limited in your upstream bandwidth by the nature of VDSL - all of those signal converging together cause significant co-interference.
Finally, I'd like to see how a "simple copper can do 1Gb" in any real world conditions. Good quality Cat5E can 1GB over 4 pairs (not a single pair), and only for 100M. When you start looking at single pairs of shitty corroded cable low diameter cable, bundled together in groups of 100, all co-interfereing, and having to travel 500M to 1km, it's a completely different story.
