It’s hard to sell a counterfeit car or GPU without someone noticing a difference.

Clothes, chargers, cables, etc are counterfeit because it isn’t nearly as obvious.

Name brand foods often come with significant markups and would be fairly easy to counterfeit premium bottled water etc. Except as the article mentions food substitutes generally happen earlier in the supply chain not at the grocery store.

The reverse also happens, knock-offs being as high quality as the name-brand because it's cheaper on the production side to use existing factories/machinery.
