Nearly every operating system distribution maintains it's own fork of most system utilities and libraries with varying levels of divergence from upstream. A piece of recent news around here was Python 2.7 being maintained by RedHat for several years beyond upstream support. Some of the differences make it upstream, some of them don't. Doubtful OpenBSD is trying to usurp the current OpenSSL team, but if they do good quality work, it might be very influential a few years down the road.
