Most distros use GNOME. Most distros use PulseAudio. Most distros use NetworkManager And now, most distros use systemd. I'll let you guess who pushed most of these? Guess who is responsible for PulseAudio, NetworkManager, systemd, libxml, gnulib, and very large portions of the GNOME project? And who is the only player that matters for commercial Linux (Oracle doesn't count since OEL is rebuilt RHEL)? Keep telling yourself Red Hat is just /etc/sysconfig and RPM (actually, RPM IS the standard package manager for Linux based on the Linux Standard Base)
