Say I have just discovered a 2038-type "feature" in an airborne system I have delivered. If I tell the regulator who issues a maintenance AD which says reboot the systems regularly, then I don't have to fix it, in fact I don't have to do anything else at all. Furthermore, if someone falls prey to it, it's now their deal for not complying with the AD and no longer my deal for building the "feature" in.
