Indeed. The thing with marketing claims is that people need a deep technical understanding of the subject to be able to discern false marketing from real marketing, and it is just not feasible, since said marketing is addressed to the masses. And even with that level of understanding there is still a chance that something could be dodgy under the hood where we can't see. With enough critical thinking/paranoia it gets impossible to consume and be happy about it, so maybe it's the case that "the less I know, the better". Simulacra and simulation, all that..
