Your point is valid. Companies do use marketing to sell their products by using lots of outrageous claims. And my problem isn’t really what the companies it’s mostly with the people who are buying that bullshit.

P.S. your Coca-Cola example would have been better if you had reached back to their origins when they were sold as a tonic that cures just about everything. What they’re being sold as right now is just a soda and all of the current marketing around it is just nostalgia bait which everybody uses for everything especially around Christmas time.
