How about non-removable batteries and unrepairable phones? Many phones would be still ok, but the non-removable (cheaply) battery means that they get replaced prematurely, because the cost of replacement is overlapping the price of a low/mid tear phones. Back in the day, you pulled the back cover off, put a new batter in, and the phone was as good as new. Same with other types of repair, especially the kinds where manufacturer just replaces the whole assembly just because of one small part malfunctioning.
