It's literally in the name - BSD is "Berkeley software distribution". NetBSD (and Free, Open, Dragon Fly) ship kernels with original tooling and integrated 3rd party software, as a distribution.
Yes it is in the name, much like Federal Express. Not a distribution in a canonical meaning of the word. The idea of distributions is unique to Linux-based systems.
>>Examples of software distributions include BSD-based distros (such as FreeBSD, NetBSD, OpenBSD, and DragonflyBSD) and Linux-based distros (such as openSUSE, Debian, and Fedora).
If you look at my past comments (and maybe my Username) you could have seen that FreeBSD is my main-system (Server, Laptop and Workstation) since well over 17 years (the servers since that long).
And yes yes i not just like it but are deeply in love with it ;)
Let us stop here, no hard feeling's and have a good one, cheers.
