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. (embedded and server-side)

While a government that's "monolithic and controlling but keeps the trains running on time" is clearly a bad thing, it's not clear that the same holds for computers -- particularly for your average user. I'm not too concerned about Apple locking down my machine as long as I can get what I want to get done done -- and that doesn't involve making my tool conform to some ideology. I have more important things to worry about -- even more important infringements on personal freedom -- and I'd rather have my tool work adequately with as little pain as possible.
