It's not really about sales. First, sales numbers can only really ever tell you part of the story. If every fridge has a screen, sales numbers won't tell you about the demand for screenless fridges. If, at that point, some manufacturer tests a screenless fridge, the sales numbers might tell you about a lack of demand or might tell you about a failure in marketing. Additionally, if fridges with screens can be used to advertise to customers, get them to sign up for subscription services, steal their data, avoid the expense of bifurcating the line of fridges, or otherwise increase profit or decrease costs, they will be manufactured anyway.
