I'm still confused... if court has accepted that he's "Satoshi Nakamoto" or only his claim over whitepaper. What does this claim really mean?
no the court didn't accept he is Satoshi Nakamoto. the scammer went to court and made a claim, the court set a date and asked the other party (cobra) to attend. they didn't attend so automatically the court ruled in favor of the scammer.
this only means that cobra wanted to protect their privacy and didn't want to give the scammer the satisfaction of doxing them.
He is really trying hard to avoid the consequences if any after he exposes the identity. May be this itself is proof that he is Satoshi? How could the court be so dumb to proclaim a unstable and too baffling person to rule a favour of the court? That's really a underrated judgement by the jury. Or may be they were simply too ignorant and had under the table thingie going on. In any case Cobra is so stubborn that they are willing to pay that huge amount just to hide the identity. That's like a real man!
