Quoted from Kneissl:Lyman should be untouchable at stern. The company is suicidal if they let him go.
Yes, which is why it's even more concerning that he appears to be very frustrated.
They should be bending backwards to keep him engaged and happy. His ability to play the game combined with his connection to the community, ability to code, and passion for the product makes him as near to invaluable as it gets. He's the engineering unicorn that every company I've ever worked for would kill for.
It bears repeating that the criticism about schedules and such are not directed towards Lyman, Waison or any of the others actually writing the code...but it must be difficult for them sometimes because their names are on the games too, not just Stern.
