Well, I disagree on that point. In my mind, the key words in the
exception are 'an executable'. At the time the exception was added,
many people believed that free OS's were the way of the future, but we
would still be using large numbers of closed-source, shrink-wrapped
apps. The exception seems to have been intended to allow userspace
programs like StarOffice to initiate scanning. This is different from
linking SANE to a library, even if that library acts as a SANE
backend. I think it is a stretch to call Brother's usage in a backend
'an executable'. Yes, a library contains executable code, but it
cannot be started from the command line without a front-end.

I also wish we could change it, but it is too late. There have been
too many authors over too many years. There is a good chance that a
few of the authors have died. It would be very difficult to identify
entire files which could have their license changed.
When I added sanei_magic, I seriously debated making it GPL. But, I
decided that I could not find a way to convert my backends (which
needed to use it) to the GPL as well.
