The internet isn't run by the government, it's mostly run by private companies. These private companies want to create and enforce a sort of tax policy around internet consumption. Companies can tax you in multiple ways (slowing page load speeds, censoring content, denying access to services etc...) and they can do it for multiple reasons (business interests, lobbying from their friends, censoring dissent etc...) Net Neutrality is the idea that private companies should not be able to create tax policy on core internet infrastructure, and instead it should remain tax-free for all users.
The ultimate irony here, is that this battle is pitched as Silicon Valley vs. the U.S. government, with Silicon Valley fighting for a free and open internet and the government trying to pass legislation to pave the way for private companies to enforce tax policy. But in actuality the battle for a free and open internet has morphed into the people vs. Silicon Valley, with tech companies as the villains in the story.
The arbitrary censorship on social media sites (such as Facebook, and Twitter) has gotten really bad. Platforms like Youtube for content-hosting and Patreon for fundraising have begun demonetizing and delisting their political opponents. Lower level infrastructure such as GoDaddy and Cloudflare have even now begun to enforce political delisting.
Wake up. Private companies are already enforcing a tax on your internet consumption if you are guilty of wrongthink. Whether it's Verizon, Twitter, Patreon or Cloudflare, who cares, it's the same thing.
