It's not about literary approach, it's about fraud. He attempted to get this book published as fiction before changing some of the content and shopping it to publisher's as non-fiction. According to SG there is still a lot of fiction left in it. If he's a former fuckup trying to help people out great. If he's fabricating most of the fucked up parts of his life and making millions in the process pretending to be someone he's not... that's deplorable.
