All those products have one thing in common. It’s what we call gourmetization in my country, which is a concept I believe the people should be aware of globally. It’s basically the process of making you believe that the simple, cheap, realiable and lasting stuff you already have lacks something, and then marketing an “improved”, refined and more expensive version to you. This process goes hand-to-hand to what you call enshittification, often being a catalyst for it.
