Ok so let's say you want to look at Brazzers, and you pay Brazzers $1/mo for access. But your ISP doesn't like Brazzers, because they get a kick-back from xHamster. So your ISP says you can subscribe to Brazzers for $1/mo, but then you also need to pay your ISP $100/mo to have access to Brazzers. So now your Brazzers subscription is $101/mo, $100 of which goes to Verizon, for providing you with access to Brazzers (along with their usual internet fees, and any other websites you would like to access), and Brazzers only gets $1/mo to produce content for you. Now you can't pay for Brazzers, so your ISP can decide which online businesses succeed and which fail, based on how much access tax the ISP wants to charge.
Say you want to apply for a job at a new company, you need to submit your CV online to their website, but because your ISP knows you want to apply for that job, it cranks up the cost of going to that website to $100/visit, so now you need to pay $100 just to submit your CV to your next job.
Say your ISP doesn't like their competition, so you can go to their competitions website - but they charge you a one-time fee of $100,000 to visit the website of their competitors: so you can never leave.
In effect, Net Neutrality will kill the internet, destroy critical infrastructure, end any semblance of personal privacy, plunge the world back into the dark ages, and probably kill all humanity off faster than a nuclear winter: when we suddenly lose access to a functioning internet - which is now critical economic infrastructure the world over.
Net Neutrality is terrorism. It eliminates the sovereignty of every nation with the first stroke of a pen. ISPs will have the exclusive ability to control access to all information, to sculpt opinion, to control knowledge, to control communication.
