What bothers me about downsizing product, is the packaging doesn't change size. I would rather pay more for the same amount then pay a hair less for much less. When the packaging doesn't change size, a greater percent of what you pay in total is for packaging.
Then you have the issue that the size you had once gotten was the perfect size for your need. Perfect example for me is Tuna Fish in the foil packet. A 6oz package was perfect for my wife and I. Now the package is 5 oz and we have to have less protein with our carbs or waste money by buying a second package just to have the same amount and risk have the remainder go to waste.
I get it, prices go up. I am not stupid. Raise the price as needed without trying to pull a fast one.
Here is another fast one that food comapnies have pulled, Ice Cream. Forget that you can't buy a half gallon of ice cream any more. But in many cases, you don't get ice cream. Take a close look at the packaging. Most say Frozen Desert.
What is the difference you ask? Frozen Dessert is made with oils as opposed to milk and butter fat.
Look at the Breyer's label. They used to promote all natural ingredient's. It no longer says Breyer's All Natural on the packaging.
Sorry for my tirade.
