everyone believes something different, everyone knows a different set of facts, everyone thinks of themselves as reasonable, and the law depends on what a reasonable person might believe. absent some objective standard of reasonability it's all just places where you can inject ambiguity and then leverage that ambiguity to make the law shift like sands in the wind while still thinking of it as absolute and immutable. "Reasonable people understand that words don't always mean what their common definition would imply and it's on the consumer to know the difference" for Sony immediately followed "reasonable people assume words mean what is implied by their common definition and it's on the producer to account for that" for the California Dairy Council, then when we accuse them of crafting separate laws for separate clients they can say "well we just applied the reasonable person standard here the same way we would for anyone else".
