There are four parties here, not two. A is the company whose products the dumpster diver B took. C is the marketplace where B lied and said the goods were as advertised by A. The aggrieved party is D, the end consumer, who thought they were buying the quality advertised by A or implied by relevant laws and regulations. IMHO, most of the blame lies with B, but experience has shown that C will almost always turn a blind eye in the name of growth. > For food at least, the expiration date is usually the manufacturer's "best by" date, meaning when they no longer back the product with their brand, not whether the food is still good to consume. This, among other practices, leads to a mind blowing amount of retailer food waste in the US. I'm all for scavengers being able to profit from what would otherwise be wasted as long as they're honest. There are legitimate ways to reduce food waste, but this is not one of them. The main problem is that dumpster divers don't advertise their wares as "scavenged from a dumpster" or "expired" or "recalled" because that would result in lower profits.
