I pity what people do to society in general with their self-destructive attitudes. We all suffer as a result when we drive people like Notch out of positions of leadership.
You see the same in politics where the truly good and earnest people are also the ones with a conscience and too much self-respect to submit themselves to the abuse of public office.
Notch just secured the best thing he could have. Now he has the money to do what he wants and not be at the forefront of what he created. Something I'm sure he's been wanting to do for a long time. Just like he said, he gets to step back into the shadows, where he's more comfortable, out of the limelight and content to do what he really wants to do.
I can only imagine what we'd be writing had he opted out say a year ago, before MS bought his company. What would we be saying then?
I really hope he finds fun and joy. I am immensely grateful to him (and the rest of Mojang) for Minecraft.
However, I think a saying I heard today summed it up quite well: "A few boos can drown out a lot of cheers."
With a sense of perspective as to what he has achieved, the people that complain must be a very small minority.
