Network neutrality is the idea that your cellular, cable, or phone internet connection should treat all websites and services the same. Big companies like AT&T, Verizon, and Comcast want to treat them differently so they can charge you more depending on what you use.
Share this with everyone you know. And tell them to do the same. No other issue will be as important going forwards. The internet is our best bet for solving any of our problems, we need to protect it.
