I am stunned this is on HN. He got _20k EUR_ for a (not fantastic) poem he quite likely didn't use more than 160 hours of work on. He played the game with his daughter for a while and then wrote this according to the article itself! How could you possibly demand more than 20k? How could he even believe he has _any_ legal case when he took the money, gave Mojang/Notch a license verbally (especially given he took the money), even if Microsoft bought Mojang?

The entire article is just egoistic/greedy nonsense.
