I used to run a small electronics repair business and you are 1 billion percent correct. Slowly watching things over the years become unrepairable was just such an obvious business decision for profit over customer satisfaction. There is absolutely no reason to make those changes unless you have a profit driven motive. So so so many electronics used to be like the fairphone your mom has. Pop it open, take out what’s broke, replace it with some OEM or 3rd party part you bought for like 2 dollars and you’re all set. It’s so frustrating nowadays with how purposefully difficult manufacturers make any repairability. Can’t even change a damn battery in your phone now! lol
