OK.  I'm pretty sure that making a donation to FreeBSD would not be 
inappropriate, at least.

Some of the software that "comes with" FreeBSD is under the GPL or LGPL, most 
notably the compiler toolchain (gcc, gdb, etc).  Questions about the GPL should 
be directed to gnu@gnu.org, for GPLed software (which is generally located under 
/usr/src/gnu):

1-sec% ls /usr/src
COPYRIGHT               etc/                    release/
CVS/                    games/                  sbin/
Makefile                gnu/                    secure/
Makefile.inc1           include/                share/
Makefile.upgrade        kerberos5/              sys/
README                  kerberosIV/             tools/
UPDATING                lib/                    usr.bin/
bin/                    libexec/                usr.sbin/
contrib/                make.conf
crypto/                 nohup.out

The rest of the FreeBSD software, contained in the other parts of /usr/src (such 
as the FreeBSD kernel and most of the "BSD userland" utilities) are generally 
under the "modified BSD license".  However, I'd imagine that kerberos is under 
the MIT license, say, and there are undoubtedly other exceptions.

It's a very open license without other restrictions or obligations.

The number of people who have written code either under a BSD-style copyright, 
or for the FreeBSD project specificly, is a fairly large and diverse group of 
people.  If you generalize broadly over a large enough group, you will find 
exceptions to almost any statement, but:

Yes, they intended to publish their software under an open source license.
No, not all of them intended to say nothing about patent rights or trade secrets.
