I've had this comment on my mind for about an hour now, and it strikes me as both correct and yet the behaviour you identify is inoffensive to me in this context.
In particular, I don't disagree with users behaving in an egocentric manner regarding their desktop environment, the software they choose, and the way their hardware operates. That's an intimate and personal space where many spend most of their waking hours; they ought to feel empowered to control and operate it as they wish.
And if that's the case, it may be warranted to have a dismissive attitude towards those who would undermine that power.
