Probably because it's write once memory? (and tied into Apple validating the serial on activation for theft prevention). It's a repair process presumably done by a certified professional who should know there is no margin for error. I really can't imagine this kind of error causing more damage than, for example, users throwing full cups of coffee over their expensive laptops. Should we ban drinking coffee close to expensive laptops too then?
