How different would the history of Linux have been had FreeBSD (and its forks) not been encumbered by lawsuits in the 1990s? Would Linux have gained the mind and market share it did or would the BSDs have won?
With the likes of Apache and Samba PCs running Linux (or a BSD) could replace many thousands of dollars in software licenses for server products for zero licensing dollars. It didn't really matter if the base OS was a BSD or Linux, as long as the services ran on top on relatively inexpensive hardware it was a massive win for a lot of organizations.
