The only thing broken on the Mac was the glass display, which I guarantee you does not cost more than $100 to replace wholesale, even with labor. However, Apple doesn't offer this repair for you. Instead, they sell you an entire topcase to replace the entire top half of your computer, even if your aluminum case, display, hinge, backlight, microphone and webcam are all fine. Your only option is replacing everything, at which point, I think OP has reason to be mad. Apple simply doesn't invest money in making their devices more repairable, they make too much money off selling replacements for it to be lucrative. That's fine, and their decision to make, but there's a real human/UX cost that comes with making fragile hardware.
