GNU/Linux is considerably easier to use for non-professional administrators. Especially well battle-tested distributions like Debian and derivatives. For example, if you want to deploy a Rails application, you can find working ‘init’ files for Debian & Co. easily. If you use FreeBSD, you have to write your own init files. It’s not hard but might be one or two hours of work for someone familiar with *BSD before you get them to work correctly. Then you have docker on linux. FreeBSD added docker support in June 2015 and according to their website is not production ready. OpenBSD doesn’t support docker. For small dev teams supporting their products or for bigger teams which work with micro-services docker is heaven-sent. It allows you to run the exact same configuration on the server, out of the box by just mapping a few ports. Likewise, there are many tutorials, howto’s, etc. which make it trivial to setup a HA-Proxy under Linux. But if you need to setup CARP+HAST under FreeBSD you have to go through the official documentation - which is top quality material - and find your way from there. It’s not a 10-minute copy/paste thing. Add to that a rather elitist culture e.g. BSD is designed, Linux is grown - roughly translated as ‘we are engineers, you are hackers’ which in many cases is not far from the truth and you have an explosive mixture which renders BSDs obsolete. That said, I find strange the fact that so many corporations choose to support GNU/Linux over BSD in terms of driver development or funding, given that the BSD license is way more permissive. This was the reason Linux picked-up early on and became way more popular than BSD among hacker, but when corporations jumped-in, they didn’t choose BSD, they went with linux. I am not sure if this was a data-driven decision or it was just a matter of technical people in decision-making positions have a lot more sympathy for Linux than BSD. At this point in time, GNU/Linux has clearly won the race. However, if someone would ask me to setup a ‘secure’ mail-server, file-server, whatever without specific requirements (e.g. docker, LVM, etc.) I’d probably go with BSD.
