The point isn't reducing an outage for FB, it would actually extend the outage for some. The point would be to help give some relief to a DNS server you're running that's overloaded due to the FB outage...during the "crisis". Yes, of course, better planning ahead of time is nice. In any case, I didn't suggest doing this. I wondered if it was happening.

I think you missed the idea that the FB outage created a really heavy DNS load on other people's DNS servers.

No, I didn't miss the idea (and it's not an idea, it really happened.) I believe you're mistaking the role of the resolver operator and whether or not they should be manipulating client queries/responses without the user knowing. An NXDOMAIN response does not match the conditions, and shouldn't be used just to manipulate the clients.
