Let's say it's fine for the FCC (or another government entity) to do this, though. What if I run open WiFi, but I block bittorrent traffic? Have I violated my neighbors' rights? I think I can do what I want with my pipe, but would this be under the FCC's authority? I'm not a business, sure, but what about the WiFi at, say, Starbucks? I trust a non-monopoly much more than I trust a government, which has a de facto monopoly over imposing its will by force on the populace.
Built into the laws of this country is an inherent mistrust of the government., the idea that authority over the populace has a corrupting influence, and that it should be kept limited to the extent possible. You hope for the best (a benevolent set of leaders) but plan for the worst (a power-hungry group of totalitarians). The Constitution's plan for the worst is to avoid trusting in our leaders' benevolence and keep them from getting enough rope to string us up. It's what I love about this country.
I think most of the commenters here agree on that principle, so I would like to apologize as it seems I've been a little abrasive, and we're all on the same side here (at least apparently). But I am secure in my belief that the government is too big already and its authority needs to be reduced, not expanded in any direction.
Starbucks free WiFi is an excellent point, which sheds light on the underlying philosophical debate. If an organization provides a resource (WiFi, water, a job), but only to a select group of their choosing, at what point do we call it supplying a service, and at what point do we call it discriminatory starvation? Is the glass half full, or half empty?
If there's competition, it's moot, but if there isn't any, we're giving the single supplier complete power over distribution (slippery slope to plutocracy argument). If we ban discrimination, it's also moot, but then we're giving government power to dictate rules for private organizations (slipperly slope to fascism argument).
