Most frontend developers also don't have much - if any - HCI/UX/design training. My experience is that a lot of people who should have had that instead see design as "above" that in a way that is worse by far by showing active disdain for user feedback. Often, in fact, by dismissing input from a user perspective from developers with a "oh, but you're not typical users". Which is on one hand usually fair, but on the other hand dismissing that they also are users, and often there is no such thing as a "typical" user.

If one segment of your users reports something as a problem, you need to at least try to understand why and whether it is possible to reconcile with what your other users want, or whether in fact your other users also would agree but just haven't been vocal about it.
