Regulating the internet means telling people what they can and cannot use.
Regulating ISPs means preventing them from telling people what they can and cannot use.
Finally! A soundbite for the Internet Freedoms that the average person can understand quickly. Frankly, the names and slogans supporting internet freedoms have been very poor. The literal name, "Net Neutrality," for example, is confusing and buys zero support. Look at the ill-considered provisions that quickly made it through Congress, they have emotionally charged meaningful names like "Patriot Act", "No Child Left Behind"
Even Cerf's quote (from the summary) "... we don't believe that governments should be allowed to grant themselves a monopoly on internet governance...," sounds rather weak. To the average less-informed person on the street, this is not compelling. If not the government, who should govern the internet? Why should one care? While it's truthful, it's unconvincing without additional context. Not a good soundbite.
Governments will always be tempted to censor or control the internet directly for their own self interest. (ex. Wikileaks) Having a central authority such as the UN do it would be a horror. The temptation to somehow tweak the traffic "to protect " worldwide would be unbearable. At least now, any national government doing so needs to establish some sort of "Great Firewall" to wall out the free internet.
Before the United States government forced aircraft manufacturers and patent holders into the Manufacturers Aircraft Association there was a patent war that resulted in lots of litigation in the United States but no aircraft manufacturing or innovation once the patent war started.
When a real war broke out, WW1, the United States had to buy aircraft from France because the United States business ventures were more interested in lawsuits than making aircraft.
After ending the patent war by forcing everyone into a patent pool the aircraft industry in the United States took off.
There are other similar cases that plainly show how the patent system has been a failure from the beginning in serving the Constitutional requirements. To promote the Progress of Science and useful Arts.
Note that the aircraft industry had to be forced into a patent pool by the US Government. This is another patent pool, but unfortunately controlled by a few giants. It's totally necessary to get business done, but excludes everyone else.
We will have solar energy as soon as the utility companies solve one technical problem -- how to run a sunbeam through a meter.
