As long as they're billed as replicas, they're not counterfeit. Replicas and clones, unless we know there's a court issued restraint against them, are a civil matter between the original manufacturer and the clone maker. Unless there is something we can recognize as a fraudulent claim of authenticity, or an obvious trademark infringement, it can become quite complicated.
Trademark infringement is usually fairly straight forward. Patent infringements have so many twists, turns, time limits, licensing and whatever, that only the patent holders, their attorneys, and the courts that try their cases can untangle the issues.
While loyalty to a brand or original manufacturer can be admirable, we may be exceeding our abilities to know when a line has been crossed, or if there even is a line. Unless there is an obvious effort to appear as a trademarked production of the original, it would likely be best to avoid any accusations.
