This got downvoted?! If you want thirty years of backwards compatibility, go use Windows (you saw how well that worked for security...). OpenBSD is an OS that people choose to use when they want security prioritized as a trade-off against other things such as performance and binary compatibility (there's always trade-offs). Many firewalls use it, for example. If you value other things more than sheer data security, then there's other (beautiful) choices. (Analogously, there's no single best vehicle for everybody.) Anyone with a modicum of actual OS kernel development experience would acknowledge these mere facts as universal truths, instead of "unpopular opinions."
