Nike determines what counts as a Nike product; it they are selling it, it is not counterfeit; It may be poorly made or made in ways you didn't expect, but nor counterfeit.
To use your own analogy, surely you must see there is a difference between someone attempting to purchase nike shoes and being tricked vs someone intentionally seeking out counterfeits (e.g. to get a deal)
My comment is wondering to what extent the clients are "tricked" vs to what extent they know (or suspect) its not the real OF model and dont care as long as the fantasy is intact.
