Good for him, personally i'd be sick of the fans too here he gives a universe to people and how do they repay him? They scream in his face and tell him he did it all wrong, and how he is a loser. Hell if I was him I would take back all of what I made, I wouldn't let people tell me what I can and cannot do with the franchise I created.
Honestly one can make the argument that he's doing exactly that.
Fans: Lucas needs to quit. He's a hack and should stay away from Star Wars.
Lucas: My fans think I'm a hack and should stay away from star wars. So I won't make anymore movies.
