All that to say, the BSD userbase as a sizeable subset that are there for countercultural reasons, rather than technical. These are the people who buy into, say, OpenBSD's vaunted security reputation, or believe that "linux bad because reasons", so you're always going to get people in here bragging, because "not using linux" has become part of their identity.
I run a mix of FreeBSD and Linux on my personal devices. The ground truth is that FreeBSD is yet another unix-like OS written in C, and thus not immune from the types of bugs that stem from that lineage. None of the BSD distros are materially more secure or better than a properly-configured and patched Linux.
