This. My uncle used to have a garage and already in the nineties was complaining that fixing cars was about to become impossible due to the addition of electronic parts that were black boxes to him. 30 years later and we live in a world where obfuscation is done on purpose.

Edit: we must start a movement of open source appliances. Cut out the middleman, buy directly the parts and assemble the thing yourself, so youu know exactly how to fix it later on. If it works for 3d printers why can't it work for kettles and dishwashers?
