Simple answer - knowledge share. Many more people know and are familiar with Linux than FreeBSD. Throw in companies like Red Hat, etc. and that makes it more compelling for those wanting some sort of support backing.

Personally, I've been running FreeBSD (including some commercial installs -- years ago) for about 16-17 years.

Pretty much this this.

Linux (especially Debian-based distros), is usually the first UNIX flavour that people coming from Windows get in touch with. While FreeBSD has excellent documentation, Ubuntu and others simply have the larger newbie-friendly community.

This sums up my experience. I still have an ISO of FreeBSD 10.1 sitting somewhere on my system just waiting for me to copy over to a USB drive once I work out how to set it up on a dual-boot system along with Windows.

So far, all the guides I've seen for dual-booting have been for Linux, and they've all been straightforward.

I agree and especially it should be noted that Ubuntu and RedHat had huge marketing budgets compared to pretty much everyone else for the last decade. Nobody really pushes for FreeBSD in business settings because there is no social capital that comes from doing so. All three require a lot of skill to manage but that skill seems lest costly for Red Hat and Ubuntu even though it's not necessarily true. That's the power of marketing.
