As I understand, it does not limit the possibility of using it as a reference for a free implementation of the *de*compression algorithm. As an example, the zip and unzip programs come from different source packages. INAL, but I see no problem in creating a GNU unrar program, as long as the code from unrarsrc is not used, just the concepts.
This is more or less what I am already trying to do, but even extracting the concepts is not easy. Unrar uses 2 decompression algorithms, a virtual machine, several filters, a lot of headers, encription, etc.
