Yes, Net Neutrality Is A Solution To An Existing Problem
Professor Barbara van Schewick, along with her "recent letter" to the U.S. Federal Communications Commission (FCC) was noted as the inspiration for this Techdirt post by Marvin Ammori.
While AT&T, Comcast, and Verizon have argued -- with incredible message discipline -- that network neutrality is "a solution in search of a problem," that's simply not true.
There are many concrete examples of network neutrality violations around the world. These network neutrality violations include ISPs blocking websites and applications, ISPs discriminating in favor of some applications and against others, and ISPs charging arbitrary tolls on technology companies.
