without meaning to sound antagonising, I think they are probably making assumptions about the users broadband speed being a lot better. I don't have figures to prove anything but I would guess the majority of people have a lot better.
I feel for you though, moved 1 mile down the road and went from same as yours to fibre optic.
Yeh I know the speed is pitiful, and any kind of download (PS4/Steam etc) just kills iPlayer and makes Netflix stream at 240p

It's just such a basic function to start/pause a download, but I guess there are many simple functions that are still missing from the PS4.
I've only found this issue really because I turned on my PS4 for the first time in nearly 2 months

Really hoping Infamous scores well.. otherwise I'll be waiting for the next PS4 exclusive..
