Exactly. And neither does the GFDL ban people from using the documentation if they work in a security field. It's an equivalent case. The DFSG does not say that any particular requirements related to a field of endeavor must be honored. This is true whether that requirement is "in order to use this software, we really need to be able to make proprietary derivatives" or "in order to use this documentation, we really need to store it on encrypted media". > > DFSG 6 does not say "anything a company might plausibly want to do, > > our software must allow them to do".

The whole point of the DFSG is to guarantee the giving of rights. Perhaps a better wording would be "giving the rights outlined in the rest of the DFSG" rather than "giving the same rights". Either interpretation does not change the effectiveness of your original argument, though, so I have to wonder why you bring it up. Unless you have missed the connection between "not discriminating" and "giving rights to people in every field", when the issue is about giving rights. I don't know how to explain that one better than I already have.
