Can someone explain to me why this is consumerism? I'm not going into YouTube to watch, due to the ads, but I have one of these (not a Stanley but very similar) and it has actually helped me buy less drinks and drink more water.
Think of stamp-collecting, but instead, you start collecting algorithmically controlled limited-edition thermos flask. The goal of these bottles were to be reusable, but people have started buying them as status symbols, just like Nike - they're not going to be used, they'll "rot" on the shelves. People are not buying them because they care about the environment, but because FOMO.
