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.
As opposed to today, where connects have terrible uploads speed because ISPs don't want you to host servers.
I've heard of people getting gigabit down, but only 16 mbps up.
