Why use OpenBSD?

Why use OpenBSD?

Unfortunately I also kind of lost faith in the BSD variants. There are a few minor things such as PC-BSD suddenly vanishing, or years before NetBSD on their mailing list admitting that Linux outperformed their "runs on any toaster and other gimmick" strategy. But one of the key issues I had was this:

I installed it (FreeBSD) on my second computer. I went out of my apartment and returned hours later. Well, the FreeBSD machine was no longer running; my linux machine on the other hand is running non-stop for months, literally. This may be a fluke, perhaps the computer had a problem - I am not saying this is really what the BSDs are all about, as I also had them installed before. But then I also asked myself "why would I want to bother with the BSDs, if Linux simply runs better?". And I haven't found a good, convincing answer to that for me to rationalise why I'd still be using the BSDs. Note: I also use Linux in a non-standard way, e. g. versioned AppDirs, but essentially Linux is simply more flexible than the BSDs (that is my opinion) and there are more users too. There will be always some BSD users, but to me they are like a dying breed. They would need to market themselves as a "runs outside the nerd bubble as well"; even Linux is still stuck in its own nerd bubble. You have to break out of it if you want to really dominate (Linux semi-does it indirectly, e. g. we can count many smartphones as Linux-driven, but I am still using a desktop computer system here, so to me this is what really counts, even if the total number is less than the smartphone users numbers).
