what is the difference between the adoption of systemd and that of X or Wayland?

aren’t those equally “mainstream” and don’t they also leave almost no chance to have an alternative (especially for the average user)?

this is a genuine question because, while I know and understand the sentiment against systemd, I realized just now that in the 20 years I’ve been on Linux many things I’ve used were kinda against “freedom”.

nothing a social media ban for <13 years old kids can’t solve, am I right?
