Reading the post and then HN comments makes me realize the average HN user lacks a lot of emotional intelligence. People are criticizing the post based on the cold hard mistakes the author made while completely glossing over the emotional introspection the author went through to acknowledge all their mistakes and finally close this chapter of their lives. Stop treating this post like you are code reviewing a PR.
The common critique is not that the author made mistakes, it's that he's self-centered, a diva, etc for feeling like he deserves a huge chunk of the worth of minecraft for writing the end-poem on a contract. He thinks he should get more, people disagree because $20k is much more that you would have expected for such a thing anyways.
