Linux is haphazard because it's really only the kernel. The analog of "FreeBSD" would be a linux distro like Redhat or Debian etc. In fact, systemd's real goal was to get rid of linux' haphazard nature... but it's ahhh really divisive as everyone knows.
I go back to early Linux' initial success because of the license. It's the first real decision you have to make once you start putting your code out there.
