So called net neutrally never existed. Today the proponents of it claim they just want all traffic tread the same. Like a public street where an emergency vehicle never flashes its lights and claims priority. That all data traffic just slogs along at the same speed - routine emails and streamed video.
But that world never existed on the internet. Content providers are paying for speed. Even the one who claim to support net neutrality, like Google and Yahoo.
Huffington Post has the data and a chart that makes the true situation very clear.
Greg Smith calls it "Net Neutrality Fans Aren't Going To Like This Chart” at Huffington Post.
