The big and egregious omission in their assertion is that this market used to used to be monopoly dial-up service. They omit sharing that in 1996 a bipartisan Congress passed the Telecom Act to end monoploy, promote competition and de-regulation, and that competition is now increasingly flourishing.
Net neutrality proponents must take info out of context to make their point because on the measures that matter most to consumers: expanding choice, falling prices and increasing competitive supply -- all prove an increasingly competitive market.
As my new one-pager proves: http://www.netcompetition.org/docs/Debunking-the-Myths-Part-2.pdf choice of broadband providers is expanding rapidly according to most recent FCC data; real prices for broadband have fallen over 50% in the last few years, and the supply of new broadband competitors continues to increase.
Net neutrality has become a smokescreen to hide behind for those who oppose competition and free markets for communications and who want to turn back the clock and return to utility regulation.
