Most users of gadgets have them as a fashion statement and these, the majority, would not want to repair anything. Indeed, they dump their latest iPhone when the new model comes out.
I on the other hand build everything that I use in computing and phones last me for years. My hobby since retiring from engineering (mechanical) spend time trying to revive computers, that have been condemned by the shop repair people, and I have about an 80% success rate. The costs for repairing these are never silly making it worthwhile. Most of those that bring their machines to me are retired or are families with school children; people who cannot jump and buy the latest fad.
The manufacturers are unlikely to change their ways because they have the majority of their customers in the fashion, throw away mentality range. Thats why I use my equipment until it dies of old age.
