Net neutrality is basically keeping the internet the way it is now. Right now, large telecoms like comcast, verizon, time warner, etc are pushing tiered internet, meaning they decide what internet traffic they allow on their networks. It makes it so they can push their content, and deny competitors and also making it so that sites have to pay these telecoms to allow their traffic. like the picture shows, the tiers will only allow access to certain things. basically, the large telecoms want to create an internet monopoly and make decisions for you on what you area can see.
what makes it worse is that these telecoms have deep enough wallets to put our crooked politicians in their corners unless we really speak up. you can help by telling your congressperson that you are for net neutrality.
its basically a big freedom issue that most people have never heard of.
