Kaminsky contacted me to say that Andresen responded to him on his website. He appears to backtrack in his support of Wright:
“I was as surprised by the ‘proof’ as anyone, and don’t 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 I’m 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.”
