I don't know... it seems to me that most of the complaints about Gimp come from people who actually use it, because people who never use it wouldn't have anything to complain about.
It also seems odd to assert that non-contributors have no right to complain on a forum where most people, most of the time, complain about things they have no direct knowledge of nor a hand in making.
