Apart from the comparison to NTDLL making no sense, you'd be wrong about the tools too. It aims to provide a basic standardized way to do most system-level management (set up networking, do DNS resolution, get a decently synchronized system clock) but it absolutely does not aim to replace more specialized tools like chrony or NetworkManager. For example, timesyncd doesn't do NTP or PTP, only SNTP.
systemd (the PID 1), journald and udev are different, though, because they're mandatory; and there's no alternative to logind while technically optional.
I came to the conclusion that people who complaining about systemd don't even understand, use or used it, like saying that everything run on PID1, just open htop and it's going to be proven wrong, or they know that, but their arguments are so meaningless that they resorted to lies
