It reminds me a little of set dressing in movies. Every sophisticated character owns a chemex, but they use a french press to make coffee onscreen. Harks back to the days of Notting Hill when we had to believe that Hugh Grant ran a failing second hand bookstore while living in a well-decorated house in central London. Do we think the author uses his Teenage Engineering pocket operators, or are they window dressing? Do we need Godel, Escher and Bach as the backdrop for a completely unrelated photo?
