Aaron Baugher has a post describing why he’s still using FreeBSD:
I’ve been using FreeBSD for probably ten years now, since discovering it on a client’s servers and deciding I liked it. We hardly ever need to compile a custom kernel now, but back then we did it a lot, and it was much simpler on FreeBSD. The ports system was also far better than RPM, the most common software distribution system on Linux at the time, which would gradually develop dependency issues after you’d used it a while. So I liked FreeBSD better at the software level.
The FreeBSD philosophy also seemed more professional and yet freer than the Linux community. The FreeBSD license is basically, “Here, take this and do whatever you like with it (including making money); just give the person who created it credit.” That’s much simpler and more open than the GPL. There’s an “Information wants to be free!” attitude in a lot of the GNU/Linux camp that I guess I got too old for.
Thanks to the FreeBSD philosophy and design and a lot of hard work by serious people, it’s a rock-solid server platform. It makes a wonderful web server, and the new stuff you can do with jails means even shared servers can let webmasters run insecure junk PHP scripts without any risk that they’ll hurt each other or the system. It also works very well with qmail and the whole suite of DJB tools for DNS and other server purposes.
