This. IMHO, the whole point of Linux has always been the unlimited possibilities for customization
The problem in my opinion is a noticeable shift in this mentality over the last several years.
At some point, mass adoption became the big goal, and the spirit of flexibility and building a better mousetrap started to lose ground to standardization and making things more user friendly. Linux is basically morphing into an open source Windows clone bit by bit. This is probably good for humanity and all, but for many it's the opposite of what drew us to Linux in the first place.
In particular, systemd is the ultimate culmination of this new mindset. Systemd is a big, all encompassing beast where you can't easily swap out components and where many packages are gaining direct or indirect dependencies on it, making it hard to run a systemd free system. It may work better and be more user friendly, but it's the antithesis of the original Linux spirit.
As to using a distro that doesn't have systemd as a default, as a former Gentoo user I can tell you it's not that simple. Systemd is undoubtedly the most disruptive thing to hit gentoo in awhile. Simply specifying -systemd use flag isn't enough, I had to straight up blacklist packages and then uninstall/replace a bunch of packages with non-systemd requiring alternatives and fix the respective breakage. I don't use gnome, however a few gnome libraries got pulled in as dependencies of various things, and it was a huge headache to clean that shit out. Meanwhile slackware has straight up dropped gnome3 because it's too much of a pain to make it work without systemd. On Debian, gimp, a graphical editing tool, has an indirect systemd dependency!
