Bitcoin did rollback the blockchain because of external reasons...a hacker had exploited a vulnerable part of the software.
You need to read that quote again...
A hacker exploited a vulnerability IN the bitcoin core client - that would not be called an external problem... Durp.
Core Client != Third Party Exchange. Get it?
Bitcoin patched a vulnerability, which caused a rollback past the invalid block (it was an invalid block, afterall, just not detected properly).
When you can show the vulnerability that VRC patched (they didn't...) then you can say it's the same.
Bitcoin devs patched a bug via a hard-fork. VRC dev team FORCED a blockchain rollback.
Are you starting to see the difference, or are you going to continue to be intentionally blind?

And so much effort too. So selfless

I never said selfless - I get entertainment and a higher post count, lol.
