The larger the network, the more expensive it costs to maintain and upgrade. Of course a tiny regional co-op ISP doesn't cost much to run. They don't have 25 million customers in 21 states, or 145,000 miles of fiber in 39 states.
I mean, jesus, this article goes all over the place. It's saying provisioning isn't expensive, and suggests that deployment cost is lowered by changing building codes to require conduit. How does that affect the 91 million homes that already exist?
The article states that net neutrality "prohibits [ISPs] from charging unjustified fees on Internet services". No, it doesn't. They can charge whatever they want for their services. They will increase the price of internet services whether or not net neutrality exists, because it is not getting any cheaper to run a giant ISP that is responsible to the shareholders of a media conglomerate.
If the author really thinks the only reason big ISPs charge high fees is because they're mean and greedy, they really are going to lose this fight, mainly from a lack of critical thinking skills.
