I think that there is completely different reason why they dont participate in improving the linux. As its fundamental mantra of "move fast, break things" is creating bigger and bigger gnordian knot, while FreeBSD mantra is being well though, designed and stable. SystemD will never get into FreeBSD. Docker is still behind FreeBSD jails (released 2000!) that are a security feature since the start. And so on. And people using and developing it, like such system, which linux is absolutely not. For fun check this beauty: https://man.freebsd.org/cgi/man.cgi?query=setfib&apropos=0&sektion=0&manpath=FreeBSD+8.1-RELEASE&format=html https://man.freebsd.org/cgi/man.cgi?query=setfib&apropos=0&s... This why we use FreeBSD. As not only its kernel but also its userspace is well designed.
