I personally can't use GIMP for shit, but that is because I am used to photoshop. In any case, the value of UX isn't just about how well experienced users can use it, it's also about how well new users can learn. Blaming a tool for skewing to far towards the experienced users is a valid form of criticism. Moreover, it is easy to have the skew without noticing. After all, developers likely move in circles with many more experienced users. There is also the potential blowback from experienced users to any kind of change.
