Those requirements are insanity. Who wrote this up? haha
A company who already has somebody for the job but is legally obligated to publish the position publicly. So they create a super specific position that fits 100% the person they want and then hire that person. That kind of stuff happens all the time.
Yeah, what really sucks is the other developper working with him (who has a 2y old kid apparently) who is now out of work because his partner went all crazy on Twitter. Hopefully he'll be able to fall back on his feet quickly and find another job.
