Re: "controversial decision to tear up existing net neutrality rules"
"so why appear to lose all sanity over their removal?"
Why do protest the removal of regulations?
Because as history has shown time and time again whenever regulations are removed these Megacorporations will do everything in their power to maximize their profits, remove any freedom of choice by destroying competition and/or swallowing smaller start-ups under their umbrella in mergers, throw massive amounts of cash at corrupt politicians to remove even more regulations to further their agenda and the customer be damned.
Take a look at what happened when the Telecommunication Act of 1996 was signed that was supposed to:
"provide for a pro-competitive, de-regulatory national policy framework designed to accelerate rapidly private sector deployment of advanced information technologies and services to all Americans by opening all telecommunications markets to competition"
Instead, the Telecommunications act of 1996 did the exact opposite, a drastic decline in the number of radio stations, long distance phone companies and television/cable companies and allowed for all the mergers to evolve into to what we have now.
