It's not decentralized in any practical manner when everyone's local clone is pointing to the same, now no longer available, origin.
This could have been mitigated by having a pre-determined fallback origin (which could very well be something they had in place - I'm not familiar with this project).
Some form of distributed authority could have been implemented as a more practical alternative to the scattered remnants that they might be left with now.
You're right, of course. My previous post was written up a bit too hasty :)
