CSW's whole thing is to exploit how people tend to believe that things aren't total lies. So when he says he's Satoshi, people think "Well, I don't believe he's Satoshi, but maybe he knew Satoshi". Or "He failed to destroy BTC with mining power like he said he would last year, but maybe he still actually has a bunch of mining capacity hidden away somewhere." Or "There's no technical way for him to irrecoverably screw with SegWit transactions, but maybe he found some bug somewhere."

But really he's completely full of shit; the vast majority of claims he makes are complete lies from front to back. (And often just a tiny bit of research will make this obvious.)
