A lot of it has to do with the fact that most people like tons of stuff removed from their bottled water which has absolutely nothing to do with purity or health, and everything to do with it tasting more pure.

With flavored drinks, this isn't necessary because it's such a mild flavor to begin with that it's easily covered.
