A product having once been ubiquitous, and it's maintenance therefore common knowledge that you'd pick up by habit, does not mean it's stupid to have to pay attention to this knowledge many decades later. Some misconceptions do exist, for example dish soap not usually being a detergent that damages the patina nowadays. While other practices are a development, like our general food hygiene standards having changed significantly, and keeping a patina on cookware therefore requiring more deliberate attention.
