One inescapable fact that was shown, if there's any sense out there, will be like a torpedo hitting these charlatans below the waterline. Dehydration is bad so drink, drink, drink, and since you have to drink, drink our product, they say but as was pointed out, cases of people dying from dehydration are almost unheard of while there is ample evidence to show that 16 people indulging in exercise pursuits have died of OVER hydration.
Dehydration is uncomfortable and has a negative effect on performance but over-hydration is downright dangerous and most of this over-hydration has been brought on by the big pharma/soft drinks companies. You see athletes and footballers/rugby players handed bottles of liquid during their strenuous activities and, by and large, they are needed. But you can't sell these bottles to such sports stars. You actually have to pay them to take the drinks so who is going to pay the companies the profits they are in this for? The wide-eyed spectator who thinks, 'If that's good enough for my favourite sportsman, it's good enough for me', despite the fact it's not remotely near being needed by the spectator is the target of the largesse distributed by the charlatans.
