A lot more than just security-- albeit that is one of the primary focuses of OpenBSD, encompassing everything from researching new mitigations to secure coding practices. https://www.openbsd.org/innovations.html https://www.openbsd.org/innovations.html If it helps to put things into perspective, NetBSD is closest relative to OpenBSD, the latter having forked over 23 years ago. The last time FreeBSD and OpenBSD shared the same tree was at Berkeley. In fact, NetBSD, FreeBSD and OpenBSD independently merged the final release from Berkeley, 4.4BSD-Lite2 in 1995. Linux users generally don't understand what it means for each major BSD being fundamentally distinct operating systems, including separately developed kernels, drivers, userland utilities, with their own developer/user communities.
