After reading this, it appears that Satoshi isn't a group of hackers, instead, it's a single person. Hearn made a smart move by posing simple questions to Craig based on previous discussions, but the imposter couldn't pass the test. It's a big shame to see Craig Wright claiming to be someone else when he is not.
I see no tangible reason why someone would return after making an exit in the first place. Craig Wright should stop making a fool of himself and instead consider new ideas that can contribute to making the world a better place, just as Satoshi has done.
