You really brushed that one off, uh? The ratio of linux devices to openbsd is quite literally a million to one. The ratio of tech companies invested in linux to companies invested in openbsd is roughly 50,000 to 1. The ratio of professional security researchers paid to find flaws in Linux vs OpenBSD is harder to quantify at the moment, but I think we can guess a trend here.

I can agree to a degree that OpenBSD takes security more seriously, and they have made very interesting design decisions to enforce their security model. But I entirely disagree that the number of "CVEs are facts" to back your opinion that it is superior.
