Depends on if the raw material consumed by usage costs a substantial part of the sale price. Personally I'd like to have flat-rate unmetered electricity and not have to think about how much I'm using, but reality dictates otherwise: if it was that way, people would use more, the power company would have to build more generators and burn more fuel, financial and environmental costs would substantially increase and we'd all lose out in the end. But none of that applies to my cable Internet connection, which as a result is flat-rate unmetered (well, up to some threshold that's high enough I forget how high it is; it's something like a few hundred gigabytes per month, more than I'm going to need); so I don't need to worry about exactly how many gigabytes I'm using. This is a good thing. The value Tarsnap provides to businesses is much larger than the raw cost of the bandwidth and disk storage, so it makes sense for it to be unmetered and give customers one less thing to worry about.
