One assumes the idea is to make windows have feature parity with linux, then try to leverage network effects for features windows has but linux doesn't, such that the "extinguish" step will follow the "extend" step.
That's called "being better than the competition" and not really what EEE was meant to describe.
I'm not sure there's any crisply definable bright line separating them. Generally embrace/extend strategies do involve trying to make extensions that some people will consider valuable.
