there's nothing wrong in being substanceless, nobody is pointing fingers because of that.
creating videos where you fake your playing is not wrong per se. those videos are a form of entertainment for some people (I don't get it but that's me). he presented him self like a much, much better player that he is and that's ok. it's his life, his face, his reputation. I find it really stupid but who cares.
main point here is that he build his reputation and earned money stealing other people ideas.
the fact that he is also incapable of actually playing, let alone create, what he stole and that he also did other deprecabile things along the way is just part of the story useful to understand the kind of mentality this guy has.
