It's also hard to innovate without a userland that is tightly
integrated with the kernel (like the BSDs). On the BSD side, we're
able to ship an entire ecosystem with exploit mitigations applied
because a basic userland is shipped and integrated with the kernel.

The way in which the BSDs are structured enables innovation across the
entire ecosystem. We at HardenedBSD are able to test and deploy
exploit mitigations across the base operating system in addition to
33,000+ packages.

In addition to Brad's observations, I opine that the fragmentation of
Linux has provided a net decrease in security posture.
