The choice of "security as an afterthought" and "never had any security holes ever" is a false choice between two extremes that don't actually exist (well, at least the second). The poster is referring to two very different approaches to software security. OpenBSD's approach is considered to be the most uncompromising in the industry, and goes further than probably most of us would prefer to go, but nonetheless serves as a good example of what's possible. You can read about it here: http://www.openbsd.org/security.html and there's also some good papers/presentations here: http://www.openbsd.org/papers/ .

I love openbsd but even their proactive approach hasn't made them immune to remote exploits

It's not about total and complete prevention, it's about reduction of risk. Your logic taken to its logical conclusion would argue against practically any risk mitigation measures at all. For instance, even SSL/TLS have not been immune to exploits.
