Considering OpenBSD and NetBSD have had two new releases just this year, and how well funded the BSDs are by major corpos who like ripping source code, I think their so called "Deaths" have been majorly overstated.
Give a BSD a try, it's a lot less like shoving systemd/apache2/red hat together and reading 300000 line long config files with documentation that clearly was never intended to be read and more like using an actual operating system designed to be cohesive.
