I'd like to question the argument for so-called "net neutrality" by comparing it to something I'll call "Postal Neutrality".
Under Net neutrality an ISP is prevented from charging users higher fees for faster service - that is the essential argument as I understand it.
Under "Postal Neutrality" the post office would be prevented from offering customers expedited delivery of letters and packages for a premium price.
You would never argue for "Postal Neutrality" but somehow "Net neutrality" makes sense?
The claim is that by somehow prioritizing certain traffic, you are putting services that don't pay for improved service at a disadvantage, well, yeah - paying for better service is a popular concept. There is the argument also that by the very nature of offering one customer increased speed/bandwidth you are slowing down all other traffic... People make that claim, but I've not seen it proven, just claimed as a possibility.
When ISPs have a financial incentive to increase speed/capacity/bandwidth they will, denying ISPs the ability to charge a premium fee for premium service removes the strongest incentive from ISPs to improve their network...
