Was he far from true? yes, openbsd is secure... but security objective makes many parts almost unusable...
That is untrue: I use OpenBSD daily as a workstation and as a server, on virtual and physical machines. It is very usable, stable and certainly as easy to use as most Linux distributions (I will grant you it is not as polished, as, say OpenSUSE or Ubuntu, for instance).
Need something that already exists?! lets do it all over, because now it will be "secure" (not that the original was insecure, it was just NIH).
Again, that is untrue: OpenBSD borrows liberally from other BSD (NetBSD/FreeBSD) and also from Linux. Most of the time, when OpenBSD decides to create a new solution, it is because the existing ones are not that good, in terms of security and stability.
Helping others fix the problems on their code? no, never! just use our unix and tools.
Again, this is completely untrue: check out the presentation Theo gave recently about the techniques OpenBSD pioneered and many other OS have adopted, including Linux: http://www.openbsd.org/papers/ru13-deraadt/mgp00001.html -- Particularly this slide: http://www.openbsd.org/papers/ru13-deraadt/mgp00030.html
Remember: OpenBSD is open-source - everything that is created under OpenBSD can (and maybe should?) be ported under other OSes... Case in point: OpenSSH.
many BSD developers, specially Theo, just use the security flag as a way to show off how good they are, and how everyone else should thank then for the universe.
But forget Linus, imagine a flame war between Theo De Raadt and Daniel J. Bernstein about security!!! that would be FUN!!
NOW, you have got a point!
