What is strange to me is how little-used BSD is, given its more permissive license.
And why not BSD? I'd mainly say mindshare, and portability to a degree. You don't have to release your source every time you port BSD to a shiny new platform. BSD code is out there (networking stacks, a handful of the base *nix utils in OSX), but the permissive license cuts both ways.
Apparently, many of your home electronics likey run QNX, and you wouldn't know it.
Every so often I get surprised as to where BSD is when I come across it.
