As the article points out, Costco just sells their own stuff under the Kirkland brand. Much Kirkland stuff is made by major US brands, and is often identical to the branded product, but cheaper. They don't bother hiding that it's their own brand.[1]
Amusingly, Costco sells their Kirkland items on Amazon. Or, rather, somebody called "ShippedFast" does. Now who's ShippedFast? They seem to be in Florida and the phone number maps to a residence. But Amazon doesn't disclose the identity of the seller.
