Two points:

1) I don't think we "disregard" player feedback. We read it and consider it, both the feedback that's in support of a particular change and feedback that isn't. Sometimes that feedback manifests itself in future changes, but when it doesn't I don't think it's fair to describe a subset of (oftentimes vocal) players not getting what they want as us blanketly disregarding the playerbase.

2) I try to give players the benefit of the doubt when I have access to information they don't. Oftentimes my response to a comment or criticism is to simply state that the assertion being made isn't true (because, again, I have access to evidence of the fact). Even if you sift out the hyperbole and the emotional knee-jerk reactions, players often make claims that just aren't accurate or don't consider perspectives other than their own. That isn't always their fault, but it makes for poor arguments.
