7zip states it's GPL with LGPL for unrar
7-Zip is open source software. Most of the source code is under the
GNU LGPL license. The unRAR code is under a mixed license: GNU LGPL +
unRAR restrictions. Check license information here: 7-Zip

ftp://ftp.rarlabs.com/rar/ or
http://www.rarlab.com/rar/unrarsrc-4.2.4.tar.gz more specifically's
license does seem to indicate that as long the text in paragraph 2 is
present in the source of the modified (unrar) code, it's ok to use...
<snip>
Distribution of modified Unrar source in separate form or as a part of
other software is permitted, provided that it is clearly stated in the
documentation and source comments that the code may not be used to
develop a RAR (WinRAR) compatible archiver.
</snip>
Which I think we are abiding by and certainly not creating an archiver.
The "unarchiver" I liked to is "approved" by the FSF for rar-v3 (both
archiver and decompressor)
