I am not aware of any exceptions. The only possible exception I see is
an explicit additional clause to the license made by copyright
holders.

These GPL's restrictions are needed to protect freedom of every user.

I agree that GPLs are hard to read. That is why Alexander Cherepanov
posted references to common reading of GPL regarding questions most
closest to our situation. I hope they are exhaustive and accurate.

Maybe http://www.gnu.org/copyleft/copyleft.html would fill you with
spirit of protected freedom. ;-)


It is a pity that a lot work were done on top of non-free unrar. I am
sorry for not bringing this whole question earlier.

We like magnum and respect his efforts. And it would be a big pity to
drop his work. That is why Alexander Cherepanov proposed a plan how to
keep this work legal till format based on fully free unrar
implementation would be ready
(http://openwall.com/lists/john-dev/2012/09/29/20 ). Does it look good
for you?

Thanks!
