Perhaps they have some security concerns. https://vez.mrsk.me/freebsd-defaults.txt - more admin time spent tweaking poor default security == more money being spent.
Many of the "points" mentioned therein are misleading, at best, if not outright wrong. There was a nice discussion / rebuttal of this article somewhere, although I can't remember where at this moment. Unfortunately, I'm just about to leave but I'll see if I can find it later.
Apologies, I just glanced at this link and I think I mistook this article for a "troll" article that has been posted and shared several times. I just looked at this article, started reading through it and it doesn't seem familiar. I don't think I've seen it before. I'm trying to find the "troll" article that I thought this was but I'm not having any luck at the moment.
