Was it based on previous software shipped by L.P (pulseaudio was a difficult exercise to say the least) ? or just because of change of decades old SystemV habits that felt heavy and potentially scary ?
I didn't conduct a scientific survey, but I think more the latter than the former; also, a lot of peoples' knowledge has been very much based on the public debate, which tends to the idea systemd offers benefits for desktops. Which may be true, but I see far more benefits for desktops.
