Last I checked, my Linux and BSD systems don't phone home. I primarily use openSUSE, Arch, and FreeBSD, with some Debian thrown in, and I know none of those phone home by default (and I don't know if there's a way to ask them to phone home). There may be other OSes in those families that do (I've heard Ubuntu does), but that's completely fine since you have a choice (I can run any Linux or BSD app on another OS in the same family that doesn't phone home).
