I mean, on one hand, yes, they are restricting the amount of bandwidth they'll allow you to consume. But let's be realistic for just a moment. Are you ever going to hit that limit?

The only ISP we have in my community has restricted bandwidth to customers for a long time. They cap you out at 100 GB per month. I work from home in a capacity where I RDP into a computer across the country, and I don't come ANYWHERE close to meeting that max. We watch Hulu probably twice a month, and I usually stream Pandora in our living room. I download music and movies online as well. I think I might have got up to 20 GB once, but I had to try hard.

If I had a dedicated IP, and was hosting my own server, I'd be concerned. If I played WoW all day every day, I'd be worried. If I watched more than 2 HD movies per day every day of the month, I'd be worried. But as it stands now, I don't notice a bit.
