One of the things that has always appealed to me about minecraft and dwarf fortress is the attitude the developers have towards their projects and their work time.
I sense a general atmosphere from certain people throughout the known world. "Notch should do this because I've explicitly bought the product" ... "Notch should do that" ... "Notch should conform to the stereotypical capitalist american ideal of 12 hour days working solidly on advancing the codebase until it represents everything it can possibly be, BECAUSE HE HAS MY MONEY." (that's no longer your money, by the way, you exchanged it for a game in development - nothing more).
And whats wrong with Notch setting up mojang to be the company he wants it to be? To work how he wants to work? At the end of the day his decisions will decide the success or failure, long term, of Mojang.
Besides, employing highly creative individuals and then making them work like Victorian coal-miners doesn't sound like a great idea. Working with your friends and taking lots of time for reflection, thought and other abstract things sounds much more fun, and who knows, more productive? Notch has the opportunity to do this with the success of minecraft, and I applaud him for doing so.
Ultimately he'll be judged long term by the quality of games Mojang put out, and the vocal minority can not lead the direction of the company with reactionary nonsense.
