"They just don't want other parts of the system to be wholly dependent on systemd."
That is really the crux of the issue and what distinguishes the systemd dispute from all the other FOSS food fights. The FOSS community never agrees on anything. That is why we have multiple everything: Multiple Kernels (BSD & Linux Kernels, multiple flavors of each) many distributions of each flavor, a host of programming and scripting languages, multiple package management tools (rpm, portage, dpkg) several GUI toolkits, GNOME and KDE desktop environments etc. Wayland is not enough, we must also have Mir. And the licenses. Egads! How many of those do we need?
Despite all the passion and ego involved, disagreement between adherents of particular designs and implementations has never before risen to the level of open revolt that we see over systemd. Why? Because in all these disputes each person can choose what is best for him/herself. Like Python and despise Perl? Use Python. Vice versa? Use Perl. But the usual rule of the user getting to pick what he likes best does not apply with systemd. Lennart Poettering is working to restrict choice to only systemd. His tactic is to make systemd a dependency of major software packages. Here he ison the Gnome dev list pushing a Gnome systemd dependency.
Sometimes an unpopular item is replaced on the buffet; Good software wins out and variety shrinks a bit. That can be a good thing. But the fear is that systmd is going to win not because it is a popular choice but because Poettering has gamed the outcome using dependencies. Something is wrong if you are running systemd because you hate it and you love Gnome. Perhaps the fanatical hatred of Poettering is driven by belief that systemd adoption is advanced in part by his cheating, instead of on the merits of systemd alone. The abusers are abusing not because he has written what they judge to be bad software but because he has violated an unspoken ethic of the FOSS community.
