Huh given the context (especially given that this was post DAO hard fork) I read that as vitalik saying that "Code is law" is a principal, not necessarily saying that "code is law" is a principal held by himself/Ethereum.
Vitalik goes on to defend against Mow's claim that he is "pivoting" by saying that it is indeed a principle. It's extremely clear with basic reading comprehension that Vitalik is claiming that as a principle of his.
Not sure how you extracted the meaning you did. If I'm being honest, you seem to not really be researching the subject in good faith, as a simple google search will turn up many times he's either stated he believes that in text or even video.
You are welcome to believe what you'd like to though, I unfortunately don't have the time to do your research for you, nor do I care to change your mind. So cheers and good luck!
For what it's worth I have passing familiarity.
Taken from wikipedia:
> The people who continued with Ethereum Classic advocate for blockchain immutability, and the concept that "code is law" against the pro-fork side (Ethereum) which largely argued for extra-protocol intentionality, decentralized decision-making, and conflict resolution.

Ethereum Classic clearly believes in code is law, that's not the chain that Vitalik works on.
I tried ~5 searches and went ~15 deep. I generally don't appreciate the "just Google it" manta, but I'd really like to know the answer to this.
