Most healthy phoronix discussion in the comments, systemd, x11 and rust too.
In my opinion systemd helps a lot, dns becomes a lot easier (like managing dns-over-tls), managing services becomes fine (even managing zram on distros without the zram configuration package), etc, so I see why they would want to change some internal stuff to use systemd, less chores on the devs.
The anti-systemd manifesto on the website: we should have 5000 different packages with no integration whatsoever to manage the OS internals like ntp, services, timers, dns, etc.
I see that a monopolizing software is bad, but it just helps make a working computer work well.
