Or maybe it's part of the entertainment value he wants us to perceive. He's fairly self deprecating when it comes to his playing, that's one way to thin out the haters by critiquing himself negatively so they don't have to.
That's a good point, but I wonder how much he'd have to negatively critique himself in order to silence the haters, and how self-critiques would affect his viewership. Seems like it'd take a lot of self-critique to silence most of the haters, and that'd be annoying for his other fans to hear.
You can't please everyone. I was a hater initially and changed due to his work either. Be yourself.
