Just because they can do 3 gigabit broadband and 4k video does not mean that they should immediately roll it out everywhere. Upgrades like this cost money and it comes with a bandwidth cost. Do they want to dedicate 20 channels for broadband or do they want to provide 80 more television stations?
And enough about bandwidth caps. We aren't normal users. Do you know for example the average AT&T broadband customer uses 21GB a month? I'm sure Comcast is similar. Sitting here typing it out I just realized that we are the 2% complaining about we should get more when the other 98% is paying most of the cost.
The average user uses far more than 21GB a month. Netflix alone will drive up that usage.
Downloading more gigabytes does not increase their cost. That is an entirely false premise based on the notion that bits are some finite resource like water or electricity that are consumed. There is no magical "bucket of bits" that has to constantly be refilled. I tend to do most of my heavy downloading overnight into the early morning hours and I can assure you that it is not taxing their resources in the slightest.
