For the most part, I think this is already the case today with a lot of products. Most people just have no idea a compressor works on a fridge or how to diagnose the problem. There's really nothing you could do to make a compressor less complicated to work with. Washers are driers don't exactly have embedded computers. They're straight forward to fix, too. Plenty of dishwashers available that are non-electronically controlled.
Most everything is fixable if you're not afraid of a screw driver and watching a Youtube on how to take it apart.
I agree with you here. I used to believe that all the appliances are not fixable due to all the comments people make like "they are not like they were 30 years ago".
In reality when I opened up some of my appliances for DIY repair I found them to be incredibly simple and easy to repair after some youtube videos. I am sure there are some examples where an appliance is not fixable but all the appliances I have owned in my life have been.
