The good thing about FreeBSD it comes with an Elixir package, whereas Elixir is not available at all for my Linux distribution of choice, CentOS. Also WhatsApp runs Erlang on FreeBSD so I guess there’s an obvious connection there 
Still, we’ve moved pretty much everything from FreeBSD to CentOS due to better support from (virtual) hardware vendors and some bad experiences running routine upgrades on FreeBSD. It’s a great OS though without the massive fragmentation that Linux has.
