I hesitate to put words into their mouth, but two things seem likely 
contributors: historical reasons, and the historical lack of embedded hardware 
ports for FreeBSD.  FreeBSD now runs quite happily on many ARM/MIPS/PPC 
boards, but this is fairly recent (last 2-3 years).  I'd like to think this 
opens up the door for a lot of new potential uses of FreeBSD, but we'll see.
