The vast majority of Linux users consider systemd as a good thing because it apparently makes system administration easier. They also don't agree that systemd is monolithic, because it's actually designed modular.
But of course there are detractors. The only thing I like about systemd is its declarative service definition and parallel service startup. But if I wanted to run an OS with bloated and inscrutable software (even with the source code), my choice wouldn't be Linux or Systemd.
I also routinely switch parts of my OS. This is harder with systemd. Although it is modular, the modules are so tightly coupled that it will prevent the replacement of modular components with alternatives. Frankly, I think systemd is killing the innovation in system component development.
Systemd is too egotistic to even mention Linux. They will simply name it
systemd-defenderd
