Fixers are reacting, sure, but they're probably reacting to far more vulnerabilities than any one breaker could find. And reacting doesn't mean that you can't be leading -- it's entirely possible for someone to say "gee, OpenSSL seems to have lots of security vulnerabilities, maybe we should avoid using OpenSSL" and thereby pre-emptively immunize themselves against a wide range of yet-to-be-discovered breaks.
As for me being a breaker... I'd say that my security-related time is split roughly 90% building, 9% fixing, and 1% breaking.
