The right has always been open with grovelling to the wealthy. From their very formation post fudalism.
Normally the wealthy are a bit better at keeping things under wraps then Musky Elon running US government departments openly breaking laws. Speaking at far right rallies attended by racists.
He seems to be the billionaire least able to STFU to keep his goals secret.
Sorry to grin at you. But in OS theory Linux is known as a monolith kernal. So you choice of words would have given my lecturers a freakout.
But while your terminology is a bit crossed. The ideal you are explaining is fine.
Better Technical way to put it. Linux is just the kernal. Much of the interface you see is actually programs or apps running above that kernal. A d can be changed amd selected.
Windows is also started multipart. But has become less so over time. And it’s single distributer makes it way less obvious. By preventing any competition within it’s internal structure. The original monolithic kernal of Windows was the MS Dos command.com program. But I no lying those of us from the 80s and early 90 remember using it.
