From the crowd funding page:
> For anyone who struggles with allergies, heartburn, acid reflux or digestion, has trouble controlling weight or cholesterol, or simply doesn't have the means to eat well, soylent is for you.
> Soylent frees you from the time and money spent shopping, cooking and cleaning, puts you in excellent health,
> By taking years to spoil
> The founders and scores of DIYers have been living on Soylent for months and there is much evidence that is considerably healthier than a typical diet.
There's no mention on the crowd-funding page that this is an experiment.
I tend to agree with you - people can do what they like with their bodies and this product would fit a lot better if it was sold as an experiment, with access to discussion forums and etc.
I notice they now have a disclaimer on that page.
