"Red Hat rules the Linux server market, and as much as you might dislike Poettering or systemd, Red Hat aren't going to start taking something as drastic from upstream as an init system change without it benefiting their core market."
That would be the core market which they can supply with the systemd-free RH6 and earlier. AFAIK pre-systemd SEL is coming to the end of support. That leaves Red Hat with the only commercially supported systemd-free product. Having your cake and eating it?
