One can even say UNIX is extincted, even Microsoft added WSL and WSA, where L is for Linux, not UNIX/POSIX and A is for Android, which is sort of Linux too. > For comparison, FreeBSD has 5. 4 of which are related to linux compat.. This sounds to me as FreeBSD is more "lean" or "clean" and even may be less "agile" and this aligns well with what I've read and heard from others on internet and in person. I don't have my own opinion here and cannot compare. What I can compare though, is FreeBSD implementing Linux compat/Linuxulator and not vise versa ( and mentioning WSL above ), giving me impression of Linux/Linus' tactic (even strategy may be?) worked better than others. Would be interesting to hear your opinion.
