> we've (society) been purchasing tons and tons of a product for who knows how long that has been inauthentic, without any idea that it was the case

Also, whenever this happens, one should stop and consider:

"Why are we buying aloe vera products in the first place, when millions of people using the product for years are unable to detect that it's fake?"

If this happened with something tangible, say replacing all regular coke with diet coke without changing the labels, it would be noticed immediately.

Whenever people buy something which they are completely unable to differentiate from a fake, are they really being defrauded when someone sells them the fake?
