Developers cause software downtime, but they usually don't cause infrastructure downtime, which is what Chaos Monkey does. Cloud VMs have failure rates somewhere around 1-2% depending on who you ask. This is low enough that you can ignore it most of the time, but it'll come back and bite you hard later. Chaos Monkey artificially forces that failure rate high enough that you'll notice problems immediately and fix them before they become too engrained into your architecture.
