There is a difference between trying to unmask satoshi and claiming to be Satoshi.
He who tries to expose Satoshi should be scorned.
He who pretends to be Satoshi should be ridiculed.
There is only one Satoshi - All of us.

I agree with the distinction.
I do not agree with "we are all Satoshi".
And what exactly does "we are all Satoshi" mean?
I'm not Satoshi, I'm just grateful Bitcoin is here.
Sure, Satoshi built Bitcoin on top of other people's achievements. Nonetheless, the novel design is a masterpiece, the planned, generous disappearance even more.
Have you seen Seven brides for seven brothers?
In the end all the girls claim to be a single babies mother.
So that their fathers don't string up the men who kidnapped them because they have fallen in love with them since. Also in Solomons judgement the one woman abdicates on her claim to be a babies parent to protect the child.
Convincing Solomon that she indeed is the mother.
Lying about identity or relation occured by Abraham lying about being married. Jacob pretending to be Esau. King David faking his sanity etcetera...
We are all Satoshi means something along those lines to me personally.
It makes the person of Satoshi ambiguous so as to protect from claims and accusations.

OK, got it: "we are all Satoshi" as a strategy to disguise those searching to identify the true one.
I was afraid it meant "Bitcoin is a collective creation" and therefore ...
Btw, I love the "Seven brides for seven brothers" parallel!
