If a product looks pretty and seems to work great at first experience, but is really an unmaintainable mess under the hood, has an unvetted dependency graph, has a poorly thought through architecture that no one understands, perhaps is unsustainable due to a flawed business model, etc., to me it simply suffers from bad design[0], which will be felt sooner or later. If I know this—which is, admittedly, sometimes hard to know (especially in case of software products compared to physical artifacts)—I would, given alternatives, make the choice to not be a customer. In other words, I would, when possible, absolutely make a purchasing decision based on how good the code is (or based on how good I estimate the code to be), among other things. [0] The concept of design is often misunderstood. First, obviously, when it’s classified as “how the thing looks”; then, perhaps less obviously, when it’s classified as “how the thing works”. A classification I am arriving at is, roughly, “how the thing works over time”.
