Perhaps, if many people in a community complain, you should assume that they have a reason to do so? And you might listen, in order to learn the source of the upset and what can be done to fix it?

Do you take the same attitude with your customers, clients, and users? It's an example of "It works on my computer:" "I don't see why they think the software is slow. So I'm not going to investigate to learn why they say the application isn't working, and I certainly am not going to try to improve its performance."
