What manufacturers are not taking into account is the simple fact that a fridge is not like a mobile phone. Most people will happily upgrade their phone annually to get the latest model often paying extortionate monthly prices to have the latest fastest shiny.
People replace their fridge when it no longer keeps their food cold. I can understand the desire from manufacturers to further build in timed planned obsolescence. But are the general public going to stand for it? I do think their is a limit to this.
