AFAIR the gnome people were desperately looking for someone who'd maintain console kit and the systemd people stepped up and provided a working alternative, so gnome switched. After the switch, systemd basically was a hard dependency for every system using a recent gnome version. If the time spent complaining about systemd were spent towards supporting alternatives, things might look different today. It doesn't require coding an alternative, but organizing support, funding a patreon etc. would go a long way.
