It's because he's an intelligence asset designed as an attack on the Bitcoin social layer. He will get away with it after some people make some phonecalls containing bribes and blackmail. 

 Very hard to believe given that he's been running long cons for decades. 

 they could have picked him up and started using him partway into his Satoshi con in order to keep it alive and make it as disruptive as possible 

 just opportunistically using their other asset from 2010, Gavin, to give the thing legs
