> He asked for their offer, Mojang offered $20k, and he took the money.
The way I'm reading it is that he didn't even want to talk about the money. It had to be all about the art. And yet he clearly has lots of feelings about the money. Like I said, it's mostly his own attitude that's his problem. And although he claims lots of personal growth because of this, I'm still not sure he really understands that he's mostly projecting his own issues on others.
Still, he's probably right that he still owns it and Mojang only had a license, and giving it to the public domain is a nice gesture, if made with some grandstanding.
