Spidey is pretty much dead on when he comes into these threads as they pop up. I'm a power user, and yeah, I love using up a huge pipe and DLing all day long.. but I UNDERSTAND why ISPs are instituting such policies. A double edged sword exists .. broadband is becoming more and more ubiquitous and so is digital (online) distribution of media (games/movies/music via the net) but because of this congestion is growing exponentially.
The problem is, consumers (power users like us) are used to how things HAVE been for years now - get a solid pipe for 50-60/mo (I pay 50/mo for 2mbytes down) and DL all you want. That was viable when the percentage of heavy users was still very low. Now that percentage has risen significantly and as such the Internet bill is going to start looking more and more like a normal utility bill.
If you turned all the facets in your house on full blast and let them run for a few days, would you not expect your water bill to increase?
If you turned every light in your house on, and then left them on for a week, would you not expect an increase in your electric bill?
The bottom line is that as more people sign onto broadband the more demand is being put on networks.. Throttling/caps was an inevitability.
