When Linux came along in the mid-90s, most commercial Unixes had left behind the Unix philosophy, with their own integrated, object oriented desktop environments and sophisticated administration tools. Only Xenix, the engine that powered many an auto shop's rinky-dink five-user database setup, stuck with the model of text terminals and CLI administration with simple tools.

Of course Linux took off, and it sort of reset everything back to stone knives and bearskins. But systemd itself is modelled on Solaris SMF, which is world-class industrial grade service management for large server deployments.

Appeals to the "Unix Philosophy" are the province of reactionary greybeards. Unix philosophy means nothing in the modern era.
