Do marketers care whether their marketing is intellectually honest? Maybe that matters if the people you're marketing to are very discerning or cynical, but I'm not sure I'd put the typical Apple customer in that bucket. As long as the marketing gets people to consume the product, I don't think it matters if it's stupid or if it's lies.

My guess is that people who work for Apple do it more because of the giant FAANG salary and the social cachet than because of the product marketing.
