>an obligation to making a big dinner is not convenient

As someone who likes to cook (and has test-driven 3 or 4 of these services), I don't see them as that at all. Blue Apron, et al are paint-by-number compared to actually cooking from a normal recipe where you have to measure and prep. I liked having them as an option, but they didn't scratch my "cooking" itch at all. They were more like a convenient way to put a decent, healthier dinner on the table in almost the same time you could do Hamburger Helper or some frozen bag meal.
