Not really. For example cable internet (and ADSL) goes thru cable (shocking knowledge, I know). Cable have limited bandwidth, and as it is just a single cable, not RX/TX pair as it is for ethernet and it has limited bandwidth
Which essentially means you have X bandwidth to distribute between upstream and downstream. And it's far more profitable to sell X 40/10 Mbit connections vs selling a bunch of 25/25 Mbit ones, where most people there won't be using upload all that much.
