'last few years' it's nearly a decade, if he was still active then there wouldn't be as much as hype about his identity.
I guess that's his sole mission; remain anonymous just like Bitcoin.
For the founder [Creator] to stay anonymous doesn't make the creation [Bitcoin] anonymous, not even it transactions.
NB: A true freedom giver will not care about fame neither will they care about the riches inclusive but, will care about the oppressed happy just because they are free at last.
Personally, I salute all successful freedom fighters and freedom givers.
