One absolutely magical aspect of the internet as it is today, is that I can stand up a server - on my desktop, on a VM in the cloud, on a physical server, wherever - and my friends can access it from all over the world. Poor indian farmers with smartphones can use my server to get data about the local market for rubber, rich financiers can use my server to educate themselves about the likely effect of new financial laws, Strip Club workers can access my server and learn about new health risks.
All of that goes away once I need to pay Comcast a bribe to persuade them to provide access to my server for their customers.
This has nothing to do with whatever commercial opportunities the Internet may or may not provide for Big Business, and I really dont care much about those.
In time my little server may start to make a profit, maybe that is my motivation when I begin or maybe not, but regardless of my original motivations The Internet is magical technology that lets people from all over the world communicate.
that is the functionality I care about, and that is the functionality that anti-Net Neutrality laws massively threaten.
