When batteries for my 2006 MBP's model had problems, Apple issued a recall. I got a new one in a UPS box that I could use to send the old one back. This cost apple parts and shipping, not even a technician's time. Service like this is much harder to provide if the computers you build are not repairable at all. They created a situation where fixing one problem means exchanging the whole unit. That is their own fault. Are you seriously blaming the customer for wanting a fault fixed in his 3kUSD computer with paid warranty extension?
