'People protect themselves from frustration by deciding not to care. So you end up with people whose attitude is, "Well, I showed up for work today. That's all I have to do. If I can't make progress, that's not my problem; that's the bosses problem.'"-- Richard Stallman in Free Software: Freedom and Cooperation1
RMS is actually talking about frustration with non-free (speech not beer) software but it describes Adam's problem perfectly. Adam clearly felt frustrated. And if you're frustrated you can either not care or become very annoyed or remove yourself from the situation. He took the latter option.
You can see in C&W Think Tank one of his efforts to become unfrustrated.
I'm not saying I agree or I care but when I read that this morning I really understood it's essential truth. And I strongly relate it to Adam's decision to quit. He wanted very much to care but was finding it increasingly difficult to do so (remember when he used to go meet little user groups and they loved him? What happened to that?) Could he have done more is of course the counter-question.
