Most of the the newest devices are perfectly repairable if the manufacturer would release the schematics and not block their suppliers from third parties buying the parts (and as newest trend lock the parts together on hardware level). Maybe not all problems but a lot of the most common ones for sure. Repair shops have managed to source new screens and cameras for the latest iPhones for example. Apple just firmware locks them to the device that stops them from working even though it is a identical part (except for the serial number burned into the chip). Basically it is not about making designs that just happen to be hard to repair but instead the manufacturers are making them intentionally hard or impossible to repair for third parties to protect their own repair line and/or force you to buy a new one especially now that phones have started to last 3+ years just fine as progress on cpu speeds have slowed done.
