His stance is not hard but stupid. Broken clocks can show correct time twice a day. He calls Windows and Mac secure compared to Linux, and evangelises users to avoid using Linux, despite the two closed source OSes being giant security targets with unknown bugs and backdoors. Micay hates AMD’s secure CPUs and prefers insecure Intel CPUs in his private chats.
Security is not that simple a concept, the way you think you are explaining. Systemd allows to manage ease of configuring security in exchange for the weaknesses a user may have in manually doing unnecessary init script chores. It is well known that systemd is more polished, standardised and simpler to use than manual init systems. Systemd is not magically using more “energy” than OpenRC or SysV. Most of these people find purpose in all the “hard work” they did in manually creating scripts and refuse to accept the new thing out of the “old good new bad” principle, and not what you claim. I have spent a lot of time with these hobbyists to understand every fiber of their thinking and superstitions.
