He does make a good point about not listening to every user-submitted change request. You can drive you self nuts trying to please everyone, but in the end you will realize you cannot.
I think his comment is a bit extreme (and not very professional). I agree with his point, but I bet even Markus reads user suggestions and some of those suggestions make it into his next set up updates.
The point should really be that you need to take user suggestions with a grain of salt, and really evaluate whether they add value to the entire community or just a small subset.
