The linked article also says the tools they use were changed to limit the amount of resources that could be taken down at a single time, the speed they could be taken down at, and a hard floor was put on the number of instances that could be stopped.

I think you have it backwards. The post does not say they will simply be training the problem away. They are putting safeguards into their tooling to prevent the case of a fat finger.

The article leaves little doubt that they didn't know such an event would be so hard to recover from. They knew it wouldn't be easy, but they were surprised by how bad it was.
