I wonder how many of its customers are too young to appreciate the reference or the irony. To them Soylent means one thing - this product. It'd be tricky to find out though, without spilling the beans. Kind of a quantum question in that way.
Given that Soylent in the book is an apparently commercially successful product that rides the wave of a Malthusian catastrophe, it's still an odd choice (or a revealing Freudian slip) given their early hype about solving world hunger.
