If I may dive into this arguement with my personal point of view, I will.
As I said on Coestar's facebook post on the MineCon shotstorm, both were under extreme stress - especially Notch (in the last three months he's married ez, finished Minecraft - that took some doing - and helped organize it's first convention), so after three days of stress, parties and sleepless nights (worrying about talks and interviews) odds are he's going to slip upand make a mistake somewhere. He's not perfect, he made mistakes, took their "jokes" a little too seriously (that said, they did take the jokes too far).
It seems to me like a massive fuck up. That doesn't make him an asshole, he just screweed up - as it seems, did they.
Both sides should just apologise and get back to macking and playing MineCraft.
