Truth in shrinking

I think companies have the duty to disclose if they are doing "shrinkflation." Its application to some products is more concerning than others. Surely, a bag of Doritos with five chips less will not be that alarming or important. But there are products and goods that affect the consumer's budget or the result of a process or the customary practices. Like if the usual cooking instructions will change the quality of the processed food (e.g., the volume of water for a brick of instant noodles). Like if the package of the ingredient is the usual measurement of a recipe (e.g., a stick of butter, a can of milk). Like if the product is the standard for a ration or usage (e.g., a tube of toothpaste should last for a month). 

In a time when brand loyalty and consumer reviews influence consumption, I think companies should assess if shrinkflation is the appropriate business strategy.
