Gimp is never going to change radically, since it has already fixed an user base from people that surprising likes that horrible usability (they are everywhere read some of the comments in this thread), the right thing to do is to leave that software with them. Therefore keeping users with bad usability habits in their own little bubble, that being said, Qt developers could join forces to create a proper open source image editing app that makes sense for MOST users.
In my experience, GIMP-hating seems to have a similar lack of specificity to Linux-hating in general. I generally suspect that people underestimate how much Photoshop has them trained.
