I only drink transparent water

(NOT dest-water, don't even try :D )
Pop science and marketing might mix very well. I've thought about this a bit and came to the conclusion that scientists are often too modest (and this is preferable) for marketing, whereas in marketing things need to be embellished, which again isn't necessarily a bad thing, but the two don't mix that well imho.
So, if you put zero cals on your soda can, that will, by default, contribute to more sales of the (god-awful digusting stomach-turning) product.
As far as embellishments go, the less there are, the better, in my experience. For example, there's a native producer for all sorts of hygiene related things: shampoos, conditioners, soaps, lotions etc etc. These are more expensive than the widely known counterparts, but the package design is laid back and not littered with all sorts of embellishments. And people still buy them. So, if you have a good product, you don't need to make it shiny.
