I was a happy user, Fedora did a great job introducing all those things on a great OS you can daily drive.
It is by chance that I booted old computers running 10 years old Fedora and every time I couldn't deny that the old one was better and I have been boiled like a frog.
I now daily drive Alpine on a modest N100, so I gave up systemd and recently gave up Flatpak because my browser just stopped working on day and it was virtually unfixable, some xdg-something cascading problems. So I just "bubblewrapped" the OS package and ignored all the xdg-something-else problems. I also got tired of every Docker/container problems so I put FreeBSD and use jails on my servers.
I am not a irrational Red Hat, systemd hater and I actually dislike writing RC scripts, or dealing with cron and anacron. But RAM is expensive nowadays and I started to use Linux because I didn't wanted to be trapped in the MS or Apple prison.
Open source is not about trapping users in one ecosystem. This is why a lot of people are getting tired of the systemd tentacles.
