I cloned the repo and searched it, but I couldn't find the porn. Was it removed, or was it only shipped with a proprietary version.
One thing I can't understand is why they didn't remove all images from the source code. As far as I know, GPL doens't force you to publish artwork under a GPL compliant license, or are the files 'a functional part of the program'? Should we make a GNU version? Let's replace Patrick with Tux, because they have similar shape. The squirrel with Kiki, because she's one too. Any ideas? Who could be Libbie?
