This is probably intentional - now that they've allowed repairing of your own devices (allowed is a bit too generous, more like strong-armed into allowing). So, they do the next-best thing... make it expensive to do self-repair (via parts cost) and cheaper to offer repairs. It's win-win. They come out on top looking good ("Oh look, we're absorbing some of the cost for repairs.") and consumers lose out. The net effect is that repair shops will also find it costly to repair.
