I am not the first to say it but Audioquest seems to be really pushing it.
Really ought to be illegal and in fact this level of dishonesty, false representation and price gouging might actually be.
Something to look into for the right person.
Here is their Wikipedia page.
https://en.wikipedia.org/wiki/AudioQuest. Wikipedia has indicated that it reads like an advertisement and apparently would welcome edits to make the entry more neutral. Also this might be a good place to start as to their corporate structure, whether they are publicly or privately owned, whether they are owned by a larger company that might find this unfortunate aspect of their operation embarrassing, etc. I really don’t know.
In the U.S. Federal government this would seem to fall within the bailiwick of the Federal Trade Commission. One may file a complaint and see where it goes.

Though the FTC has to prioritize amongst many bad actors in terms of their workload, I am sure.
A state attorney general or a state consumer protection agency might be interested also.
The problem with an individual lawsuit is that they can probably hire better lawyers while an individual would have trouble affording it, and proving fraud in a civil suit between private parties is very difficult. Plus the law as to advertising in the U.S. is pretty lenient by what you might call moral or values-based standards.
AudioQuest is a fair target, if, as Wikipedia states, they are the largest player in the audiophile cable market space. If you think what they do is wrong, they would make a good test case or example for a state or Federal review of such practices.
Hope this helps.
