I don't actually see that though, taken a look at their repo, they only seemed to remove branding and easter eggs to distance themselves from the GIMP project. They even went so far as to linger on versions and not merge features from GIMP, so they were actually behind. That would be what I mean by hate fork. Nothing technically good has been done with the repo.
Edit: I think they wanted to change the UI abit too for better accessibility, which would actually be a technical change for once, but other than that I don't see anything contributed to better software.
