Particularly, this is not an isolated event. Yes, in case this was an isolated event and we were to be challenged on this, we could not reason for a universal rule for lying. However, given that this is a complex situation, while we are indeed failing in what may be expressed in terms of duty, who is going to challenge us on this? Therefor, this is a totally hypothetical argument. Its meaning is really that we can't build general rules on particular exceptions. And, if we were to be challenged on the morality of our proceedings, this had to be broken down to individual actions and the conformity to general rules.
The really interesting aspect, however, is this: just by statistical weight, an AI trained on an English corpus comprising mostly anglo-saxon reception of Kant, should arrive at different productions than its sibling trained on a German corpus, which may include a more genuine reception.
