I don't believe that. There are many ways to express an opinion about Linux software, e.g. by writing about it, or by rejecting some software, or by adopting some different software.
I don't use systemd on my systems, I prefer sysvinit and openrc, and I sometimes express my arguments for why. Why would I have to write my own init system just to express my opinion that for some usecases, other software is better than systemd?
