No, there is no requirement to pay for any of the products of the
FreeBSD project.  Those are mostly licensed under the 2-clause BSD
license, but some parts of the sources are licensed differently,
including 3-clause BSD, 4-clause BSD, GPLv2 and CDDL, and the ports
collection includes all sorts of software and all sorts of licenses,
including some with rather more restrictive terms.

If you have any further questions about FreeBSD licensing, please
contact the FreeBSD Foundation (info at freebsdfoundation.org) as this is
one of their areas of responsibility.

	Cheers,
