I think Debian considered it to be non-free, see the package page[0] and
the copyright page[1].

However, 'unar'[2] can also extract rar files and is free
software[3]. It is on my TODO list. (But I am busy studying right now
and the program uses gnustep which is something I am not familiar with.)
John, if you like you can look into it.
