I think that's fair. I've been in situations where there are kind of "manufactured emergencies" which boil down to a sales conversation on a deadline which ends up getting rescheduled anyway. I have very little tolerance for that.
In the case of Fog Creek during Sandy, because the software we hosted provided planning and project management for a lot of people, going offline would have a pretty large ripple effect. Sure maybe 95% would've been fine, but I knew of customers who e.g. managed emergency services and crisis response, and so keeping them online was meaningful to me.
