His work ethic has been criticized in the past because features introduced in one version of Minecraft would be abandoned by the next and remain incomplete. Bugs would remain unfixed for long stretches of time. There wasn't a public bug tracker (if there was any at all), so users had to list bugs themselves on a fan wiki page.

To claim that criticm is "antisocial" and that we should instead treat him as a best friend to have a beer with is an odd notion. Unless Notch is your personal friend, he is just a programmer working at a company, and the only relationship you have with him is as a customer. If you sell something, get used to criticism.
