I think the argument they are referring to is the one that because there were tasty flavors, the products were targeting youth... as if adults do not enjoy tasty flavors. That's one way regulators rationalized bans on vaping products. No one is making similar arguments to ban tasty liquor.
I haven't ruled out that they were trying to target youth with their products, but having nice juice flavors is the furthest thing from a smoking gun, and yet it was presented as one.
