I was curious about the upload issue recently and learned that it is because of limitations of the old cable infrastructure. You presumably receive your internet over coax (which can still provide really good download speeds, I was surprised when my gigabit internet package came and it only had a coax port instead of fiber). Cable TV is pretty much all downloads, with only a small portion of the bandwidth reserved for uploads, since uploading is only needed for authenticating your subscription, pay-per-view purchases, etc. Unfortunately there isn't an easy way to re-allocate the upload bandwidth, because this splitting is implemented with actual hardware frequency filters that are buried and on poles all over the US.
