I don't understand how this would have helped yesterday.

They will learn and improve for sure, but I don't understand how "firmware default to your own network" would have help here.

Can you elaborate a bit please?

This is why you should have Routers that are Firmware Defaulted to your own network.  ALWAYS

Be it Calix or even a Mikrotik which you have setup with Netboot - having these default to your own setup is REALLY a game changer.

Without it - you are rolling trucks or at minimum taking heavy call volumes.
