I think the actual goal is to control everything.
To satisfy the control freak.
And yes, it is the M$ way of seeing things.

Yes. They want you to use their stuff, and in their way.

The _stated_ goal, initially, was a better service, a daemon babysitter.
It is a legitimate goal because "industry standard" one, SysV,
leaves a lot to be desired.

But then it suddenly started having unrelated functionality
added to it. Again. And again.

Yes. You are agreeing with me: they are control freaks.

I only care to the extent necessary to figure out how,
and whether it is possible, to cooperate with the people on the project.

It's possible to cooperate even with people with whom you have
lots of disagreements in details.
When someone's core desire is to make you use _their_ code,
and not being able to switch parts with reasonable expenditure
of time/effort, it is not possible for me.
