Also is a bad excuse to ignore feedback, like you seen in latest release the developers are still moving thing around like the app menu, if a user would have complained about it an year ago you all would have defended Gnome design , now the devs said it was useless and not used and is a great design to remove it. The solution is to do more usability tests and not rely on what some "expert" thinks an UI should be.
Sometimes, the problem is simply that some users really are using your software wrong. Not compared to how you think they should be using it—compared to how everyone else is using it, and so (via usability tests) how you're building it to be used.
Or, to put that another way: https://xkcd.com/1172/
Before you rebut: I'm not saying that that's true in this case. (I'm not saying it's not, either; I don't know enough about this case to judge.) I'm just clarifying the reasoning behind the general principle. People hate change no matter how justified and evidence-based it is. So inevitably, in a project, there's going to be some number of bug/issues filed where the underlying motivation comes down to "the user wanted to whine because they had to learn something new." It's not an excuse to ignore all user-filed bugs/issues; it's just an argument against people who insist that 100% of user complaints should be taken seriously. There is a "malingering quotient"—a certain percentage of complaints (different for each project) that comes down to people trying to avoid the work of coping with change.

The truth is one more more Gnome3 designers that had the vision on how Gnome should look, that branding should be non optional, they did not know what XFCE is.
People just hate change (esp. change that requires them to change how their own stuff works to accomodate it—such as devs when their platform changes), regardless of whether the given makes for a more or less coherent experience; and regardless of whether the person complaining would have liked the system more or less if it was already like that in the first place.
