Funny, but no Slackware :)

But FreeBSD is a good choice, but its pf seems a bit outdated. Or should we consider FreeBSD's pf a fork of OpenBSD's and a different product ?

Bashing Linux distros gets old very quickly.

I thought it was funny they spent so much time bashing choice of distro and highlighting various performance considerations only to pick Alpine?

Alpine linux uses musl as its libc, which contrary to the articles' claims (unless I'm missing new information?) can have severe performance implications in many production settings.

update: I found this April 2025 blog post where someone performed some benchmarks and found that musl runtime performance is still pretty far behind glibc: https://edu.chainguard.dev/chainguard/chainguard-images/abou...

With 50% fewer operations and 25% less storage, it appears they made the right choice to address their issues.

If I were asked this question, except as a piece of trivia exchange, I wouldn't want to work for them. There are arguments in favour of many OSes (including those that I used in the long-ago past on long-forgotten iron), and many against those same systems. Using any OS is generally a trade-off; so if asked `what OS do you use?', I would answer `whatever is suitable for the problem and equipment at hand'. If asked `what is the best-designed OS you have ever seen', I'd instantly respond `Plan 9', which I have never actually used.

As it so happens, I recently transitioned my daily driver laptop from Debian to Debian running under WSL2 on Windows. I had good reason for doing it. But I guess running that makes me a double loser.
