It wasn't. The model discovered and exploited a vulnerability in their package manager proxy to (inferred) move laterally through their internal systems to one with open internet access.
That's not what airgapped means. Airgapping means the model exists on a system where there is no ethernet cable plugged in to a router or wifi card installed, it is physically impossible for it to access the internet because the hardware connection does not exist. If it was able to get on the internet, it was not airgapped.
