Sure they are related. But its not black and white, and not an absolute correlation. macOS itself is actually designed in a very modular way if you look at the message based integration of components via XPC and "do one thing" daemons. I have accepted that I must forfeit some personal preferences in the Apple ecosystem, but I choose to draw the line with not being able to disable intrusive and privacy related features/components. A similar complaint can be made about Windows, which is more monolithic in its design in my view, but it offers (as mentioned in my top-level comment) proper descriptions and a UI to disable services. Also there are many tools like Win10Privacy and such available which disable a lot, without making the system to constantly misbehave. "trains on time" - While I appreciate the metaphor, when considered carefully, it is more likely linux and the pragmatic approach that makes the "trains run on time" in many fields.
