Actually, there are plenty of access providers with 2:1 ratio (more ul
than dl). It's not a matter if you're access provider or not, it's a
matter if you offer decent upstream speed or not.
In my experience, someone with 10/10 megabit/s ETTH compared to someone
with 24/1 ADSL will download the same amount of data on average, but the
10/10 will have four (4) times more upload usage, bringing the ratio from
2:1 (Dl:Ul) on ADSL to 1:2 (Dl:Ul) on ETTH.
So because Comcast is offering low upload speeds, they'll have low
outgoing amount of traffic compared to incoming. With more and more ISPs
offering more symmetric dl/ul speeds, we'll approach 1:1 ratio more and
more...
