To most people, "counterfeit" does not mean literally the same product, produced by literally the same people, even if the company who commissioned the build didn't want some of those units to be released onto the market.
Personally, I dislike the suggestion that an identical product is "counterfeit" merely because the company that commissioned the product is seeking to constrain supply and keep their price point artificially high.
The contracts between the manufacturer and the client are unknown to buyers. If the contract is being breached, the client would probably be wise to seek to enforce the agreement.
I understand there are potential trademark implications (but afaik they're not necessarily cut and dry, IANAL), but IMO this doesn't classify something as a counterfeit product, at least as far as general usage is concerned. I make no comment on the legal classification/terminology.
