Is OpenBSD really free?

OpenBSD is all free. The binaries are free. The source is free. All parts of OpenBSD have reasonable copyright terms permitting free redistribution. This includes the ability to REUSE most parts of the OpenBSD source tree, either for personal or commercial purposes. OpenBSD includes NO further restrictions other than those implied by the original BSD license. Software which is written under stricter licenses cannot be included in the regular distribution of OpenBSD. This is intended to safeguard the free use of OpenBSD. For example, OpenBSD can be freely used for personal use, for academic use, by government institutions, by non-profit making organizations and by commercial organizations.
