The answers are mostly truthful, if a little misleading. You'd get the same response if you took your car into a dealership for repairs and asked why the genuine Toyota parts are more expensive than the third-party options. It seems fair, there might be more quality control and fit & finish on the manufacturer-supplied part than a second source. The dealer/Apple repair shop will also stand by the part if there is a problem.
However (mostly) with cars, use of a second-source part does not void the warrenty. For example, Ford can't require Ford-branded oil in your car.
