Systemd was designed in a way that was more tightly coupled than the alternatives and made adopting it an all-or-nothing proposition, and other projects (particularly Gnome) were also tightly coupled to it. It was absolutely foisted on people: a lot of people didn't want it but found they were nevertheless obliged to install it. The whole thing abused the goodwill of the free software community: systemd folks added systemd-dependent patches to other software, taking advantage of the norm of accepting such contributions, while refusing patches that made systemd compatible with other systems (e.g. non-Linux). And the end result was a state where you can no longer fork and replace components piecemeal - the whole free software ethos, the very reason GNU was built as a Unix-like system in the first place - which does far more to discourage participating in free software development than any mere internet argument.
