Net neutrality is NOT FOSS!
Indeed. I was trying to find comments about this and was surprised that yours seem to be the only one. Both original-original article and the rebuff discuss FOSS and copyright questions and barely touch on net neutrality, which is supposedly the primary topic. Weird.
It is a violation of the property rights
Err... Well... Aghm... Yes, it's a restriction on the property holder. However I would argue that it's far from unreasonable for two reasons:
1) Broadband access is highly monopolized. There is usually at most two half-decent providers in an area (one in my area, some might have decent cable, DSL and optical but it would be a huge exception). Where there is a monopoly there is no market and there has to be oversight. There aren't that many entities that hold a power to oversee and government is one of these entities.
2) Internet has become a pretty vital information source in todays society. And if we like internet providers to phone companies, net neutrality provisions would be like preventing phone companies from reducing call quality for outside long distance providers forcing to use theirs long distance. Or blocking any other company that provides similar services (conf. calls, remote voice mail, etc.).
Ultimately, if I subscribe to "10Mbit internet" as a service I should be able to use it however I want, be that making skype calls or downloading videos. They can put use caps, limit throughput or do many other interesting things to make sure they stay afloat but IMO discriminating one service over the other as they please violates the concept of what internet is.
