He got turned down for a lot of jobs (in shitty ways) despite having published some reasonably successful open-source libraries? How is open source to blame for him not getting a job exactly?
If you are the author and you are reading these comments, hear this: mental illness is a serious condition that can quickly degrade your life to nothing. It is not unbeatable. Just seek medical examination explaining your situation. If your joy of development is back it may mean your worst part of the episode is already over, and with assistance you will be back on track much sooner. Good luck!
Edit: Of course, I have no real insight into this person's mental state, it just pattern matched for me with long circuitous paranoid emails a schizophrenic friend of mine used to send me.
I just hope the author does not take his life, his thoughts are barely coherent and this entire gist is disturbing.
