There will always be scam artists trying to sell things and make them sound like science. It's been going on since the days of the alchemists, with all the gizmos they came up with to 'turn lead into gold.' Maybe even longer. The explanations are just more complicated now, with bigger words. It never hurts to debunk this kind of thing (though sometimes you risk helping their advertising by giving them more name recognition or word-of-mouth) so posting a bit of explanation online where someone who takes the time to google it before responding to an ad might see it, isn't such a bad thing.
