It looks like the project is really careful not to include copyrighted materials in their distribution.
Source code automatically generated from copyrighted binary code is a derivative of copyrighted code, though. It’s like taking a copyrighted book and running it through Google Translate and then clean up the sentences manually. You could be lucky that a publisher might not care about a translation into Icelandic but if you were to auto-translate a French version of a book into English and try to distribute it in the US, you’d probably get in trouble even if you leave out all graphic artwork.
