Exactly. Doritos and Mountain Dew thrive on this concept of "amplitude", and they're palette annihilating crap for which "moderation" is so far removed from typical consumption that it hardly even enters into the model. Amplitude is at its core, a trick on the senses, and once you're out of your teens/twenties it's not a very nice one.
I would also point out the difference between traditional sources of "amplitude" (mayo is a good example mentioned in the article, fish sauces would be another) are almost always condiments, sauces, or soup bases. There is a difference between the expectation that you use some mayo on your sandwich, and the expectation that you should drink soda.
