Disingenuous ISP marketing tactics
The problem is that ISPs are addicted to marketing services as "UNLIMITED" which are not, and never have been, "unlimited".
I've never had a problem with any ISP managing their bandwidth in a reasonable manner. If people don't like the service and bandwidth they are providing at the price they are charging, they are free to find another provider more to their liking.
But because the marketing arm of most ISPs just can't wean themselves from flogging "UNLIMITED" service packages, the bozos resort to sneaky measures to try to throttle users traffic usage in various ways, instead of BEING HONEST ABOUT WHAT THEY'RE SELLING.
That's the main problem in a nutshell. If all customers knew exactly what their service was paying for (X amount of data transfer per month, not to exceed X amount of data in any 24 hr period, for example), there would be no need to "secretly" throttle this-and-that.
The other issue are the ISPs that are trying to choke off services that they think compete with something they're trying to sell. (ie ATT and Google Voice) I think it should be obvious to anyone with a few brain cells that that is unacceptable. Especially if it's done surreptitiously.
Apparently the large cellular providers are trying to claim that they need some sort of special dispensation because their available bandwidth is lower. I call BS: all they have to do is abide by the same principles above, and they're no different than any other ISP - just like Genachowski said.
Once again - they just can't bring themselves to admit publicly that 3G cellular data customers can't download as much porn via their mobile as they can at home over cable.
In other words: DUH.
