The point I was trying to make is that the customer didn't want "better," they wanted the "same" even though it was crappy. The post I responded to seemed to want an example of that.
On your points, I agree mostly but in this case people didn't want better quality. They liked the taste of the lower quality product.
In that case, it's not "lower quality product" now, is it?
It may use ingredients that score better on certain metrics (low sodium, etc.) but these don't mean"better quality" in the sense that these consumers are interested in (the taste that they've come to like.)
