Your point is fair. The idea with ethereum is that oracles will be able to have a much finer granularity; whether this allows for more useful apps still remains to be proven by us in the ethereum community. (Also, there are plenty of folks like myself working on oracle-free apps, but since these are based on unproven economic models at this point, it would be negligent for us to promote them widely before we have evidence that such designs work in practice, on the live ethereum blockchain)
