I don't think that's the whole story. Even national brands like McDonalds have subtly changed their packaging to feel less artificial and more "earthy", for lack of a better term, even if the product itself hasn't changed. There's an awareness of a cultural shift. I would guess that processed/high-sugar foods today are where cigarettes were in the 90s. Everybody knows and accepts how bad they are, many people have changed their habits accordingly, many people haven't. Digital media on the other hand is more like where cigarettes were in the 70s. Most people know roughly that they're bad for you, but few do anything about it.
