I think the problem is logistical. Unless another company turns over their customer base who bought the 757 with order numbers to CS, which I doubt they have or will do, how can CS verify customer claims? There may be a way to build an interrogator in the update installer, to verify a valid customer, against another company's copyright protection scheme, but that may violate another company's copyrights. The only other way would be manual, the customer would have to send CS a copy of the email receipt from another company, which CS can verify ownership, but that will take resources that CS doesn't have or is not willing to provide. So there are no easy answers here, and the customer is caught in the middle.
