"Re-engineering" is vastly overstating what they should do. PayPal has a reputation for systems screwing up almost exclusively in their favor, mostly by hanging on to money for far longer than they should. Hence the unwillingness to "re-engineer" anything even past the point when you can assume it's anything but acting in bad faith.
