If Chaos Monkey had been responsible for setting off a global outage, I could imagine business leaders getting cold feet about using a tool like this. In traditional companies, anyways, they'd never have seen the benefit of it and after only hearing the costs, they'd probably be livid that a widespread outage had been caused by something like this.
Widespread outage is exactly what something like chaos monkey is intended to help prevent. Even if this were chaos monkey induced (seems very unlikely), they've gained far more stability by having it than they would have lost in a single outage
One could make an Arrested Development episode where George Sr. and Lucille hear about this concept and decide to apply it to their children.
(Edit: the Arrested Development <-> Netflix tie in didn't even occur to me until after writing the comment.)
Resilient systems take longer to build, and thus are more costly. It is not always wise to spend that much resources on this for, say, a startup.
After a startup is crushing it, then maybe they can start rewriting any brittle monolithic systems into something more resilient.
Big companies do though they call then interns.
> Chaos Gorilla is similar to Chaos Monkey, but simulates an outage of an entire Amazon availability zone.
