His reputation along with Gavin's is tarnished.
To be fair to Gavin it looks like he wasn't really paying attention to how Wright was playing things and now admits he got it wrong:
Yeah, what the heck?
I was as surprised by the proof as anyone, and dont yet know exactly what is going on.
It was a mistake to agree to publish my post before I saw his I assumed his post would simply be a signed message anybody could easily verify.
And it was probably a mistake to even start to play the Find Satoshi game, but I DO feel grateful to Satoshi.
If Im lending credibility to the idea that a public key operation should remain private, that is entirely accidental. OF COURSE he should just publish a signed message or (equivalently) move some btc through the key associated with an early block.
