I don't know who is this guy, like many others I've never heard of him.
But yes, I would decline such accusation. And the reasons are many:
1. Since I know I cannot prove it cryptographically that I am Satoshi, I would be just another Faketoshi.
2. I guess that many reporter and madman would be looking me up, disturbing me and my family with good and bad, including hate.
3. If I would become somewhat convincing that I could be Satoshi, some may want me dead or come for my alleged money.
4. A convincing enough Satoshi could do very bad to Bitcoin (as price and also as community and development).

So why bother? It cannot do anything good neither to me, nor to Bitcoin itself.
