Is selling / monetizing open source a zero sum game?

Most of the feedback users send to us privately is good, but not all of it. We do get some negative feedback every now and then, though we try not to get too worked up about it. In a way negative feedback is good too, because at least a user cared enough to bother to shed light on an issue that was troubling them. We can (and do) resolve most issues users commonly report to us by making technical fixes to TurnKey, but sometimes users complain about things we can't change. Except perhaps to try and explain our thinking better.
