The moment we let government enforce "net neutrality" is the moment we lose the internet.
Yeah, because the moment we stop letting ma bell screw everyone sideways, all the phones stopped working. You do realize, the moment you let your ISP determine that only the most profitable traffic gets through on time, you have lost the internet as well, right?
I can buy my phone, gas, electricity, insurance, etc. from more places than I can get data access at a reasonable speed. I have exactly two choices for data above dial-up speed. I can buy my natural gas from 3, and my electricity from 6. I can get data at over 1 Mbps from exactly one provider. That is not a free market.
I'm all for a free market, and the government staying out of it, but they are already deeply in it by enforcing geographic monopolies. Also, the government can already monitor your speech, and frankly a business probably has more ability to actually censor you than the government at this point. Heck that cease and desist letter might be upheld by a court, odds are the government loses with 1st amendment cases.
The argument for not enforcing net neutrality is very, very weak.
You want to force them to open up their networks to be resold, let real competition in every town, and enforce honest advertising with full disclosure of bottom line costs and the service actually provided? Then yeah, we don't need net neutrality.
