Totally valid point, but look at the alternatives for people without the time and money to buy nice ingredients and cook for themselves. I used to eat fast food nearly every day out of convenience and because I didn't know how to eat better. Frozen dinners are no better.
It's not that I think food executives don't know what they are doing. In fact, I believe they are knowingly lowering the nutritional quality of affordable food.
So while they might not have experience in the food industry, at least the soylent folks are focusing on the nutrition of their customers as opposed to pure profit.
