A lot of the time, the person who takes this stance tend to forget that execution matters more than the idea being objectively correct. Good "politics" is about persuading the actual people who have to own and execute that idea. There are bad situations where you find yourself opposite people who add little value that is obvious and yet demand they be persuaded or else they will stand the way of your idea. When the emotional burden of fighting such battles crosses a certain threshold you feel burn-out and give up. This threshold is high for people who can do office politics well and it is low for most self-described techies. This does not mean that latter kind of people don't create the same emotional stress for others through their own political schemings (yes, even without knowing consciously, we are all political animals in our own ways – we wield what powers we have to attain our agenda, in however good or bad ways we do it).
